Explanation

Force is defined as mass multiplied by acceleration, which has the unit kg·m/sec² (or Newton). Work is defined as force multiplied by distance (Work = Force × Distance), which yields the unit kg·m²/sec². Therefore, kg·m/sec² is the unit of force rather than work.

Explanation

Selling Price = Cost Price × (100 - Loss%) / 100

Substituting CP = 3,75,000 and Loss = 15%: Selling Price = 3,75,000 × (85 / 100) = 3,750 × 85 = 3,18,750

Explanation

By Newton's second law of motion, Force = Mass × Acceleration. The SI unit of mass is kilogram (kg) and the SI unit of acceleration is meter per second squared (m s⁻²). Multiplying these gives the unit of force as kg m s⁻², which is defined as one Newton (N).

Explanation

When a fair dice is cast twice, the outcomes yielding a sum of 10 form the sample space S = {(4, 6), (5, 5), (6, 4)}, giving n(S) = 3.

Outcomes where 5 appears at least once form the event set E = {(5, 5)}, giving n(E) = 1.

Using conditional probability, the required probability is n(E) / n(S) = 1/3.

Explanation

Explanation

Tropical cyclones that originate over the North Atlantic Ocean, Caribbean Sea, Gulf of Mexico, and the Northeastern Pacific Ocean (east of the International Date Line) are referred to as hurricanes.

Explanation

The Jallianwala Bagh Massacre occurred on 13 April 1919 in Amritsar, Punjab, when British troops commanded by Brigadier-General Reginald Dyer opened fire on a peaceful gathering of unarmed civilians celebrating Baisakhi and protesting the arrest of nationalist leaders Saifuddin Kitchlew and Satyapal. Taking place in early 1919, this tragic event is the earliest historical occurrence among the given choices.

Explanation

The least number which leaves a constant remainder r when divided by a set of numbers is given by the formula: Required Number = LCM(given numbers) + r

First, calculate LCM(9, 16, 20, 24): 9 = 3² 16 = 2⁴ 20 = 2² × 5 24 = 2³ × 3

LCM = 2⁴ × 3² × 5 = 16 × 9 × 5 = 720

Adding the required remainder of 3: Required Number = 720 + 3 = 723

Explanation

The chin is a structural anatomical feature of the lower jaw (mandible) and is not a sense organ, whereas eyes, nose, and ears are all primary sensory organs of the human body responsible for sight, smell, and hearing.

Explanation

Explanation

Mahila Samriddhi Yojana (MSY) is a micro-finance scheme implemented under channelizing agencies like the National Backward Classes Finance and Development Corporation (NBCFDC) and National Scheduled Castes Finance and Development Corporation (NSFDC).

Explanation

The pattern used to code ORANGE as PTDRLK adds increasing consecutive integers (+1, +2, +3, +4, +5, +6) to the alphabetical positions of each letter: O (+1) = P R (+2) = T A (+3) = D N (+4) = R G (+5) = L E (+6) = K

Applying this same rule (+1, +2, +3, +4, +5) to the word MANGO: M (+1) = N A (+2) = C N (+3) = Q G (+4) = K O (+5) = T

This results in NCQKT, which is Code 4.

Explanation

Simple Interest (SI) is given by the formula SI = (P × R × T) / 100, where P is the principal, R is the rate of interest, and T is time in years.

Since the principal amount P is the same in both cases, the ratio of simple interest depends only on the product of rate and time (R × T):

SI₁ = (P × 5 × 6) / 100 = 30P / 100 SI₂ = (P × 8 × 3) / 100 = 24P / 100

Ratio SI₁ : SI₂ = 30 : 24 = 5 : 4.

Explanation

The SI unit of radioactivity is the Becquerel (Bq), named after the French physicist Henri Becquerel who discovered radioactivity in 1896. One becquerel is defined as the activity of a quantity of radioactive material in which one nuclear decay occurs per second (1 Bq = 1 disintegration per second).

Ruminants, such as cattle, sheep, and goats, have a complex stomach divided into four compartments: rumen, reticulum, omasum, and abomasum. The rumen is the largest compartment, accounting for approximately 80% of the total stomach capacity in adult animals. It functions as a primary fermentation vat where dense populations of anaerobic bacteria, protozoa, and fungi ferment cellulose and other complex carbohydrates into volatile fatty acids that the animal absorbs for energy.

Explanation

Visva-Bharati was founded by Rabindranath Tagore in 1921 at Santiniketan, West Bengal. Tagore established it to create a unique center of learning that integrated traditional Indian concepts of education with global cultural exchange, guided by the motto "Yatra visvam bhavatyekanidam" (where the world makes its home in a single nest). In 1951, an Act of Parliament declared Visva-Bharati a Central University and an Institution of National Importance.

Explanation

Venus is often referred to as Earth's twin because of its similar size, mass, density, and overall internal structure. Venus has a radius of about 6,052 km, which is roughly 95% of Earth's radius, and its mass is approximately 81.5% of Earth's mass. Both terrestrial planets formed in the same inner region of the solar system around the same time from similar primordial material.

Explanation

Digestion in humans begins in the mouth, where mechanical breakdown occurs through chewing and chemical digestion starts as salivary amylase breaks down complex starches into simpler sugars. The process of digestion is completed in the small intestine, where enzymes from the pancreas, intestinal secretions, and bile fully break down carbohydrates, proteins, and fats into basic nutrients suitable for absorption into the bloodstream.
