SSC CGL Tier 1 2017 General Awareness Questions with Solutions

Explanation

For an object moving at a constant speed, the distance covered is directly proportional to the time elapsed. This relationship is defined by the formula s = v × t, where s is distance, v is the constant speed, and t is time. This mathematical expression takes the form of a linear equation y = mx, which results in a straight line when plotted on a coordinate system. On a distance-time graph, time is typically represented on the x-axis and distance on the y-axis. Because the speed is constant, the rate of change of distance with respect to time does not vary, meaning the slope of the graph remains uniform throughout. Consequently, the graph produced is a straight line, where the steepness of the slope represents the magnitude of the constant speed.

Explanation

An array is a fundamental data structure in computer programming defined as a collection of elements of the same data type stored in contiguous memory locations. It allows multiple values to be grouped together under a single identifier or name. Individual elements within an array are accessed using an index or subscript, typically starting from zero. This homogeneity ensures that each element occupies the same amount of memory, allowing for efficient mathematical calculation of the address of any element based on its index. Arrays are used to manage large sets of related data efficiently, providing a way to organize and manipulate data sequences through loops and various algorithms.

Explanation

Nylon is a synthetic polyamide fibre known for its exceptional tensile strength and elasticity. It was the first fully synthetic fibre, produced using coal, water, and air without any natural raw materials from plants or animals. A nylon thread is remarkably tough and durable; in terms of tensile strength, a nylon thread of comparable thickness is actually stronger than a steel wire. Because of this superior strength and resistance to wear and tear, nylon is extensively used in manufacturing products that require high load-bearing capacity, such as rock climbing ropes, parachutes, and fishing nets.

Explanation

Electroplating is an electrochemical process where a thin layer of a desired metal is deposited onto the surface of another material using an electric current. In this setup, the object to be coated acts as the cathode, while the metal to be deposited serves as the anode. Both are immersed in an electrolytic solution containing ions of the coating metal. When a direct current passes through the circuit, the metal ions in the electrolyte are reduced at the cathode, causing them to bond to the surface of the object and form a uniform metallic layer. This technique is widely used in industry to improve the appearance of objects, provide corrosion resistance, and increase surface hardness.

Explanation

Natality is a demographic parameter that represents the birth rate within a population over a defined period. It quantifies the addition of new individuals through reproduction, whether by live birth, hatching, or germination, which subsequently increases the initial population density. In population ecology, natality is a key factor in determining population growth rates and is typically measured as the number of births per unit of time relative to the size of the population. By contributing new members to the group, natality directly influences the age structure and the overall growth dynamics of a species within its habitat.

Explanation

Pradhan Mantri Ujjwala Yojana was launched by the Prime Minister in May 2016 with the specific objective of providing clean cooking fuel to women belonging to Below Poverty Line households. The scheme provides financial assistance of Rs. 1600 for each LPG connection to eligible families, covering the statutory deposit, a regulator, and a safety hose. By promoting the use of Liquefied Petroleum Gas, the initiative seeks to replace traditional, health-hazardous cooking fuels like firewood and coal, thereby reducing indoor air pollution and improving the overall health of women and children in rural India.

Explanation

Charles Macintosh, a Scottish chemist, patented the first practical waterproof fabric in 1823. He developed a method of bonding two layers of cloth together using a thin layer of natural rubber dissolved in coal-tar naphtha, which was a byproduct of gasworks. This innovation created a textile that was completely impermeable to water while remaining flexible enough for clothing, leading to the creation of the first modern raincoat. These garments were subsequently named Mackintoshes in his honor and provided the foundation for the commercial production of waterproof outerwear.

Explanation

P.V. Sindhu secured a silver medal for India in the Badminton women's singles event at the Rio 2016 Olympic Games. She reached the final after defeating high-ranking opponents such as Wang Yihan and Nozomi Okuhara, ultimately falling to Spain's Carolina Marin in a three-set match. This achievement made her the first Indian woman to win an Olympic silver medal and the second Indian badminton player to win an Olympic medal after Saina Nehwal's bronze in 2012.

Explanation

Ustad Ahmad Lahouri is widely recognized by historians as the chief architect of the Taj Mahal, which was built between 1632 and 1653 under the patronage of Mughal Emperor Shah Jahan. Contemporary historical records, including the writings of Lahouri's son Lutfullah Muhandis, identify him as the principal designer responsible for the layout and structural planning of the monument. Lahouri was a master of Persian-style architecture and was also credited with designing the Red Fort in Delhi. His expertise in mathematics and geometry was central to achieving the precise symmetry and grand proportions that define the Taj Mahal, integrating elements of Indo-Islamic architecture such as the large bulbous dome, four minarets, and extensive use of white marble with intricate pietra dura inlays.

Explanation

Bob Dylan was awarded the Nobel Prize in Literature in 2016 for having created new poetic expressions within the great American song tradition. The Swedish Academy recognized his vast body of work which effectively fused the power of poetry with the medium of song, drawing from diverse influences such as American folk music, the blues, and modernist literature. This award was significant as it marked the first time a songwriter had been honored with the Nobel Prize in this category, highlighting the literary merit of his lyrical compositions and their profound influence on contemporary culture and social movements.

Explanation

India 2020: A Vision for the New Millennium was authored by Dr. A.P.J. Abdul Kalam and Y.S. Rajan, outlining a roadmap for India to become a developed nation by the year 2020. The Great Indian Novel is a satirical work by Shashi Tharoor that reimagines the story of the Mahabharata in the context of the Indian Independence Movement and post-Independence politics. My Country My Life is an autobiographical book written by the veteran politician and former Deputy Prime Minister Lal Krishna Advani. Since the authors attributed in all three statements are incorrect, the combined option 1, 2, and 3 represents the set of incorrect statements.

Explanation

China achieved a significant milestone in its naval modernization by launching its first domestically built aircraft carrier, known during its development as the Type 001A and later commissioned as the Shandong, in April 2017 at the Dalian shipyard. While the country's first carrier, the Liaoning, was a refurbished Soviet-era vessel, the Shandong was the first to be designed and constructed entirely within China. The vessel utilizes a STOBAR (Short Take-Off But Arrested Recovery) system with a characteristic ski-jump ramp to launch fighter jets. This development was a clear signal of China's intent to build a blue-water navy capable of long-range power projection, occurring amidst rising geopolitical tensions in the Asia-Pacific region and the South China Sea.

Explanation

Chitwan National Park in Nepal is the direct northern continuation of India's Valmiki National Park, which is situated in the West Champaran district of Bihar. These two parks are separated by the international border but belong to the same ecological zone known as the Terai-Duar savanna and grasslands. This transboundary landscape is critical for the conservation of mega-fauna like the Royal Bengal tiger and the Great One-horned rhinoceros, as it allows for unrestricted movement of wildlife across the border. Chitwan was established as Nepal's first national park in 1973 and was later designated a UNESCO World Heritage Site due to its significant biodiversity and unique ecosystems that merge with the Indian protected forest area.

Explanation

The current account in the Balance of Payments (BoP) records the net flow of transactions between a country and the rest of the world that are not related to financial assets or liabilities. It consists of three primary components. First is the trade balance, which tracks the export and import of physical goods, also known as merchandise trade. Second is the balance of services, or invisible trade, which includes sectors like tourism, transportation, and software services. Third is the net unilateral transfers, which are one-way payments such as workers' remittances, gifts, and grants where no factor service is rendered in return. The sum of these three components constitutes the current account balance, reflecting whether a nation is a net creditor or debtor in its day-to-day economic interactions with the global market.

Explanation

The demand function expresses the relationship between the quantity of a commodity that a consumer optimally chooses to purchase and its market price, ceteris paribus (holding other factors like income and preferences constant). In consumer theory, this is derived from the utility maximization problem where a consumer selects a bundle of goods that maximizes their satisfaction subject to a budget constraint. Mathematically, it is often represented as q = f(p), where q is the quantity demanded and p is the price. According to the Law of Demand, this function typically shows an inverse relationship, meaning that as the price of a good decreases, the consumer's optimal choice for the quantity of that good increases.

Explanation

The Reserve Bank of India (RBI) is the nation's central bank and falls under the exclusive legislative authority of the Union Government. According to the Seventh Schedule of the Constitution of India, which distributes legislative powers between the Centre and the States, the Reserve Bank of India is specifically mentioned under Entry 38 of List I (Union List). Additionally, Entry 45 of the Union List covers the broader subject of banking. Because matters related to currency, coinage, legal tender, and the regulation of the country's monetary system require a uniform national policy, they are placed within the Union List to ensure the Parliament has sole power to legislate on them.

Explanation

Under Article 249 of the Indian Constitution, the Rajya Sabha is empowered to authorize the Union Parliament to legislate on any matter specified in the State List. For this to occur, the Rajya Sabha must pass a resolution supported by not less than two-thirds of the members present and voting, declaring that it is necessary or expedient in the national interest for the Parliament to make such laws. This resolution remains in force for a period not exceeding one year, although it can be renewed for additional periods of one year at a time. This constitutional provision highlights the Rajya Sabha's role as the representative body of the states, providing a mechanism for federal intervention in state subjects when a national priority arises.

Explanation

Vellanvagai was the category of land designated for non-Brahmana peasant proprietors in the Chola administration. The term is derived from Vellan, which refers to the Vellala community of peasants, and vagai, meaning a type or category. These landholders were the primary tax-paying subjects of the kingdom, and their agricultural surplus formed the backbone of the Chola state's revenue system. Inscriptions from the Chola period, such as those found in Tamil Nadu, provide a detailed classification of land based on ownership and usage to ensure systematic tax collection and social organization.

Explanation

Sher Khan, the founder of the Suri Empire, decisively defeated the Mughal Emperor Humayun in two successive major battles. The Battle of Chausa was fought in 1539, where Humayun's forces were caught by surprise and suffered heavy losses, forcing the Emperor to jump into the Ganges to save his life. This was followed by the Battle of Kanauj, also known as the Battle of Bilgram, in 1540. Sher Khan's victory at Kanauj led to the complete collapse of Mughal power in India for over a decade. Humayun became a fugitive and was forced to go into exile, eventually finding refuge in the Safavid court of Iran under the protection of Shah Tahmasp.

Explanation

Water covers approximately 71 percent of the Earth's total surface area, while the remaining 29 percent is comprised of landmasses including continents and islands. The vast majority of this surface water, about 96.5 percent, is found in the oceans as salt water, with the remainder existing in glaciers, ice caps, groundwater, lakes, and rivers. Since the scientific measurement of 71 percent falls directly within the range of 70 to 80 percent, this bracket accurately describes the global distribution of water on the planetary surface.

Explanation

Contour ploughing involves ploughing along the natural elevation contour lines of a hill or slope. By following the horizontal curves of the land rather than ploughing up and down the incline, the furrows and ridges created by the plough act as a series of natural barriers. These ridges break the flow of water as it moves down the hillside, significantly reducing its velocity. This mechanism helps to prevent the topsoil from being washed away, decreases surface runoff, and allows more time for rainwater to infiltrate the soil, making it a highly effective method of soil and water conservation in mountainous and hilly regions.

Explanation

The female reproductive system consists of two ovaries, which serve as the primary sex organs responsible for producing ova and hormones like estrogen and progesterone. These ovaries are positioned in the pelvic cavity of the lower abdomen as a paired set. This anatomical arrangement means that there is exactly one ovary situated on each side of the uterus. They are held in place by various ligaments, including the ovarian ligament and the broad ligament, maintaining their specific location on the left and right sides of the abdominal region.

Explanation

Algae are the primary photosynthetic organisms in aquatic environments, encompassing both freshwater and marine habitats. It is estimated that at least half of the total carbon dioxide fixation on Earth is carried out by algae through the process of photosynthesis. During this process, they utilize solar energy to convert carbon dioxide and water into organic compounds, while simultaneously releasing oxygen into the environment. This massive scale of carbon fixation makes them the most significant contributors to the global carbon cycle and ensures the replenishment of dissolved oxygen levels in water bodies, supporting the survival of diverse aquatic life forms.

Explanation

Phylum Arthropoda is the largest phylum in the animal kingdom, encompassing over two-thirds of all named species on Earth. The defining characteristic of this phylum is the presence of jointed appendages, as indicated by the name itself, where arthros means joint and podos means foot or leg. These animals possess a segmented body typically divided into a head, thorax, and abdomen, and are covered by a tough exoskeleton made of chitin that protects the body and provides points of attachment for muscles. Locusts and butterflies represent the class Insecta, scorpions belong to the class Arachnida, and prawns are members of the class Crustacea. All these organisms exhibit bilateral symmetry, an organ-system level of body organization, and an open circulatory system, which are hallmark traits of the Arthropoda phylum.

Explanation

Uniform circular motion is defined as the motion of an object traveling at a constant rate along a circular path. In this type of motion, while the direction of the object changes at every point, the magnitude of its velocity remains constant. This constant magnitude of velocity is what we call speed. Since the object covers equal distances along the circumference of the circle in equal intervals of time, the speed is described as uniform. Even though the object undergoes continuous acceleration directed towards the center of the circle due to the change in direction, the term uniform specifically refers to the unchanging nature of the speed throughout the motion.

Explanation

Lateral inversion is the phenomenon where the left side of an object appears as the right side in its mirror image, and vice versa. When light rays from an object strike the smooth surface of a plane mirror, they reflect such that the angle of incidence equals the angle of reflection. The resulting image is formed at the same distance behind the mirror as the object is in front of it. Because the mirror reverses the direction of the light rays along the axis perpendicular to its surface while maintaining their vertical and horizontal positions relative to that axis, the front-to-back reversal results in the characteristic left-right swap observed by the viewer.

Explanation

The COUNTIF function in Microsoft Excel is a statistical function designed to count the number of cells within a specific range that satisfy a single predefined criterion. It utilizes a standard syntax of =COUNTIF(range, criteria) , where the range defines the group of cells to be examined and the criteria determines the condition—such as a number, expression, cell reference, or text string—that a cell must meet to be included in the count. For instance, the formula =COUNTIF(B2:B10, ">100") evaluates each cell from B2 to B10 and returns the total count of those containing a value greater than 100. This function is essential for conditional data analysis and reporting within spreadsheets.

Explanation

Crystallisation is a process where a solid forms from a solution, melt, or gas, resulting in a highly organized structure known as a crystal. It is classified as a physical change because the chemical composition of the substance remains identical throughout the process. During crystallisation, molecules or ions simply arrange themselves into a specific geometric lattice without undergoing any chemical reaction or forming new substances. For instance, when copper sulphate crystals are formed from a saturated solution, the resulting solid is still chemically copper sulphate. Since the change involves only the physical state and arrangement of particles and can typically be reversed by re-dissolving the solid, it is a physical rather than a chemical transformation.

Explanation

When vinegar, which is a dilute solution of acetic acid (CH₃COOH), reacts with baking soda, which is sodium bicarbonate (NaHCO₃), an acid-base reaction occurs. This chemical reaction produces sodium acetate, water, and carbon dioxide gas (CO₂). The chemical equation for this process is: CH₃COOH + NaHCO₃ → CH₃COONa + H₂O + CO₂. The rapid formation and release of carbon dioxide gas are what cause the characteristic fizzing and bubbling observed when the two substances are combined.

Explanation

Salinity is defined as the total amount of dissolved mineral salts present in seawater, typically expressed in parts per thousand (ppt). The global average salinity of the oceans is approximately 35 ppt, which means that there are 35 grams of salt dissolved in every 1,000 grams of water. This concentration is maintained by the continuous cycle of water evaporation, which increases salinity, and the influx of fresh water from precipitation and rivers, which decreases it. In most open marine environments, the salt concentration consistently falls within the range of 30 to 35 ppt.

Explanation

The Shyama Prasad Mukherji Rurban Mission (SPMRM) was launched by the Government of India in February 2016 to drive integrated development in rural areas. The scheme focuses on creating Rurban clusters, which are defined as a group of geographically contiguous villages with populations between 25,000 to 50,000 in plain areas and 5,000 to 15,000 in desert, hilly, or tribal regions. These clusters are specifically selected because they exhibit latent potential for growth and economic triggers. By providing urban-standard infrastructure such as piped water supply, sanitation, improved road connectivity, and digital literacy alongside economic activities and skill development, the mission seeks to transform these rural areas into economically vibrant and socially inclusive regions, thereby reducing the rural-urban divide and curbing distress migration to cities.

Explanation

Neon was discovered in 1898 by the British chemists Sir William Ramsay and Morris W. Travers in London. The discovery occurred through the process of fractional distillation of liquid air. After chilling a sample of air until it liquefied, the scientists slowly warmed it and captured the gases as they boiled off at different temperatures. Neon was the second of three noble gases identified by the duo using this method, following krypton and preceding xenon. They identified the new element by the brilliant red-orange glow it emitted when placed in a vacuum tube and subjected to a high-voltage electrical discharge. The name neon is derived from the Greek word neos, meaning new.

Explanation

The International Cricket Council (ICC) awarded the hosting rights for the 2019 Cricket World Cup to England and Wales. This decision was part of a long-term scheduling arrangement for ICC major events, confirmed years in advance of the tournament. It marked the fifth time that the Cricket World Cup would be held in England and Wales, following the 1975, 1979, 1983, and 1999 editions. The tournament was designed to utilize various historic and modern cricket grounds across both England and Wales, serving as the premier one-day international competition for that cycle.

Explanation

Gol Gumbaz is the mausoleum of Mohammed Adil Shah, the seventh Sultan of the Adil Shahi dynasty. It is situated in Bijapur, now officially known as Vijayapura, in the state of Karnataka. Built in the 17th century, the structure is renowned for its massive circular dome, which is one of the largest masonry domes in the world. A significant architectural feature of the monument is the whispering gallery, where the unique acoustic properties allow even the softest sound to be echoed multiple times across the vast interior space.

Explanation

The Padma Vibhushan is the second-highest civilian award of the Republic of India, instituted on January 2, 1954. It is awarded to recognize exceptional and distinguished service in any field, including service rendered by government servants. The award ranks immediately below the Bharat Ratna and above the Padma Bhushan. Recipients are honored for their outstanding contributions to various disciplines such as art, social work, public affairs, science and engineering, trade and industry, medicine, literature, education, civil service, and sports. The announcement of the award is made annually on the occasion of Republic Day.

Explanation

Malala Yousafzai was designated as a United Nations Messenger of Peace by Secretary-General António Guterres on April 10, 2017. At the age of 19, she became the youngest-ever person to be appointed to this position, which is the highest honor bestowed by the UN Secretary-General on a global citizen. Her specific focus as a Messenger of Peace is to promote girls education and advocate for the right of all children to receive schooling, building upon her previous work as a Nobel Peace Prize laureate and founder of the Malala Fund.

Explanation

Myanmar is not a member of the South Asian Association for Regional Cooperation (SAARC). While Myanmar shares geographical borders with South Asian countries, it is geopolitically classified as a Southeast Asian nation and is a prominent member of the Association of Southeast Asian Nations (ASEAN). Although Myanmar has expressed interest in joining SAARC and currently holds observer status, it has not been granted full membership. The organization consists of eight member states specifically located within the South Asian subcontinent, a group that does not include Myanmar.

Explanation

For a normal good, the income elasticity of demand is positive, meaning there is a direct relationship between consumer income and the quantity demanded. This relationship is expressed by the formula Eᵢ = (Δ Q / Q)/(Δ I / I) > 0, where Q is the quantity demanded and I is the consumer income. Because the correlation is positive, the movement in demand follows the same direction as the movement in income. When a consumer's income falls, their purchasing power for standard goods is reduced, resulting in a decline in the quantity of those goods they are willing and able to purchase. Thus, the demand for a normal good decreases specifically when there is a decrease in the consumer's income.

Explanation

In the theory of the firm, the relationship between marginal cost and average cost is determined by the mathematical property that the marginal value pulls the average value toward it. When the short run marginal cost (SRMC) is less than the short run average cost (SRAC), each additional unit produced costs less than the current average, causing the SRAC to decrease. When the SRMC is greater than the SRAC, each additional unit costs more than the average, pulling the SRAC upward. Consequently, the SRAC curve stops falling and starts rising at the exact point where it equals the SRMC. Since the SRMC curve stays below the SRAC curve while the average is falling and moves above it as the average begins to rise, the SRMC curve must intersect the SRAC curve from below at its minimum point. This point represents the most efficient scale of production in the short run where d(SRAC)/dq = 0.

Explanation

The Seventh Schedule of the Constitution of India specifies the distribution of legislative powers between the Union and the States through three lists. Entry 4 of the Union List (List I) explicitly mentions naval, military, and air force works. This ensures that all matters concerning national security, defense infrastructure, and the operational requirements of the armed forces are under the exclusive jurisdiction of the Parliament. Centralizing these works allows for uniform standards, strategic planning, and coordinated management of the country's defense assets across all territories.

Explanation

The state of Uttarakhand has 5 parliamentary seats in the Lok Sabha. These constituencies are Tehri Garhwal, Garhwal, Almora, Nainital-Udhamsingh Nagar, and Hardwar. This allocation was determined under the provisions of the Uttar Pradesh Reorganisation Act, 2000, which led to the creation of the state. These five seats allow the state to be represented in the lower house of the Indian Parliament based on its demographic and geographical layout. Among these, the Almora seat is specifically reserved for candidates from the Scheduled Castes.

Explanation

Delhi, historically known as Dhillika, was first established as a capital city by the Tomara Rajputs in the 8th century. Historical traditions and inscriptions credit the Tomara ruler Anangpal with founding the city around 736 CE. Under the Tomara dynasty, the city developed into a significant political and commercial hub in northern India. It served as their primary seat of power until the mid-12th century, when the Chahamanas of Ajmer conquered the region. The establishment of Dhillika by the Tomaras laid the foundation for Delhi's long-standing status as a central capital for various subsequent empires and dynasties.

Explanation

Actual resources are those resources whose quantity is known and which are currently being used in the present. These resources have been surveyed and their quality and quantity have been determined for use. The development and utilization of actual resources depend on the level of technology available and the cost involved in extraction. Examples of such resources include the coal deposits in the Ruhr region of Germany, petroleum in West Asia, and the rich dark soils of the Deccan plateau in Maharashtra. These resources contrast with those where the entire quantity may not be known or which are not being used at present due to technological or economic constraints.

Explanation

The Earth's crust consists of two main layers with distinct mineral compositions. The continental crust, which forms the large landmasses, is primarily composed of silica and alumina. Due to the predominance of these two minerals, the continental mass is often referred to as Sial, a name derived from the first two letters of silica (Si) and alumina (Al). These chemical constituents make the continental crust relatively light and less dense compared to the oceanic crust. The presence of silica and alumina in the form of silicate minerals like feldspar and quartz is characteristic of the granitic rocks that make up the bulk of the continental lithosphere.

Explanation

In biological classification, the family is a taxonomic rank that groups together related genera based on shared vegetative and reproductive characteristics. The three genera Solanum, Petunia, and Datura are all placed within the family Solanaceae. This family is commonly known as the nightshade family and belongs to the order Polymoniales. Members of this family are characterized by specific floral features, such as a persistent calyx and axile placentation in a superior ovary. Solanaceae includes a diverse range of plants, from essential food crops like potatoes and tomatoes to ornamental flowers and medicinal herbs.

Explanation

Members of the class Chlorophyceae are commonly called green algae due to the presence of the photosynthetic pigments chlorophyll a and chlorophyll b. These pigments are localized within distinct chloroplasts and give the organisms a grass-green color similar to higher plants. The cell wall of these algae is typically rigid, consisting of an inner layer of cellulose and an outer layer of pectose. Most species store food as starch in specialized bodies called pyrenoids, which are located within the chloroplasts and contain protein in addition to starch.

Explanation

A coelom is the primary body cavity in most multicellular animals, located between the body wall and the digestive tract. In embryonic development, a true coelom is defined specifically by the fact that it is completely lined by the mesoderm, which is the middle of the three primary germ layers. This mesodermal lining forms the peritoneum, which supports and protects the internal organs. The presence of a mesoderm-lined coelom allows for the independent movement and growth of internal organs, provides a hydrostatic skeleton for certain organisms, and serves as a medium for the transport of nutrients and waste. The classification of animals into coelomates depends entirely on the presence of this mesodermally lined cavity.

Explanation

Convex and concave mirrors are classified as spherical mirrors because their reflecting surfaces are sections of a hollow sphere. In a concave mirror, the reflection occurs from the inner, caved-in surface, whereas in a convex mirror, the reflection occurs from the outer, bulging surface. Both types follow specific geometric principles derived from a sphere, such as having a center of curvature, a principal axis, and a focal length defined by f = R/2, where R is the radius of the sphere from which the mirror is cut.

Explanation

When an object moves through a fluid, which includes both liquids and gases, the fluid exerts a resistive force that opposes the motion of the object. This frictional force exerted by fluids is scientifically referred to as drag. Drag acts in the direction opposite to the relative motion of the object, effectively slowing it down. The magnitude of this force depends on several factors, including the speed of the object relative to the fluid, the shape and surface area of the object, and the viscosity of the fluid itself. For example, airplanes and aquatic animals possess streamlined bodies specifically designed to minimize this drag, allowing them to move more efficiently through their respective environments.

Explanation

An image organiser is a specialized software application designed to manage digital photographs and graphics files. It serves as a central interface for viewing, sorting, and managing large collections of images stored on a device. These tools typically include basic editing features such as resizing to adjust image dimensions for different platforms. Tagging functionality allows users to add metadata or keywords to files, which simplifies the process of searching and filtering through vast libraries. The drag and drop interface enables intuitive organization of images into specific albums or categories without manually moving files between physical disk directories. Additionally, image organisers provide integrated export options that streamline sharing pictures through e-mail or sending them directly to a printer for physical copies. Professional and consumer-grade examples include applications like Picasa, Adobe Bridge, and various built-in photo management tools on operating systems.
