Show answer & explanationHide answer⌄
Answer: (B) larynx
Explanation
The larynx, commonly known as the voice box, is the primary organ responsible for sound production in humans. It is located at the upper end of the trachea or windpipe. Within the larynx are two muscular ligaments called vocal cords, which are stretched across the internal cavity. When air is forced out of the lungs and passes through the narrow slit between these vocal cords, it causes them to vibrate. these vibrations produce sound waves, the pitch and volume of which are controlled by the tension and thickness of the cords as adjusted by surrounding muscles.

Show answer & explanationHide answer⌄
Answer: (B) 20mm
Explanation
The vocal cords, also known as vocal folds, are two bands of smooth muscle tissue located in the larynx. The length and thickness of these cords are primary factors in determining the pitch of an individual's voice. In adult males, the vocal cords are typically longer and thicker than those of females due to the influence of testosterone during puberty. The average length of vocal cords in men ranges between 17 mm and 25 mm, with 20 mm being the standard approximate measurement cited in biological and anatomical studies. This greater length contributes to the characteristically deeper and lower-pitched voice found in men compared to women, whose vocal cords usually measure between 12.5 mm and 17.5 mm.

Answer: (D) Real
Explanation
The real exchange rate measures the relative price of foreign goods in terms of domestic goods and serves as a key indicator of a country's international competitiveness. It is calculated by adjusting the nominal exchange rate for differences in the price levels between two countries. The formula is generally expressed as RER = e × (P / P), where e represents the nominal exchange rate (defined as the amount of domestic currency per unit of foreign currency), P is the price level in the foreign country, and P is the price level in the domestic country. This calculation determines how many units of a domestic good are required to purchase one unit of a foreign good. Consequently, a change in the real exchange rate reflects changes in the purchasing power of a currency relative to the prices of actual goods and services across borders.

Explanation
The Northern Plain of India is a vast physiographic division formed by the alluvial deposits of three major Himalayan river systems: the Indus, the Ganga, and the Brahmaputra. Stretching over 2,400 kilometers from west to east, these plains were created through the continuous deposition of silt and sediments brought down by these perennial rivers and their numerous tributaries from the Himalayan mountains. The Brahmaputra river system, originating in Tibet and entering India through a deep gorge in Arunachal Pradesh, flows through the valley of Assam. Its heavy sediment load and extensive flooding cycles have been instrumental in the development of the fertile eastern section of the plains. This geological process transformed a massive structural depression at the foothills of the Himalayas into one of the most fertile and densely populated agricultural regions in the world.

The sliding friction is _______ than the static friction.
● Correct
● Not quite — the correct answer is highlighted
Show answer & explanationHide answer⌄
Answer: (D) smaller
Explanation
Static friction is the force that resists the initiation of motion between two surfaces in contact. At a microscopic level, every surface has irregularities that interlock with those of the opposing surface when an object is at rest. To start motion, a significant force is required to break these interlocked bonds, a value known as the limiting friction.
Once the object begins to slide, the irregularities on the surfaces do not have sufficient time to interlock as deeply as they do when the object is stationary. This leads to a decrease in the frictional resistance. The relationship is defined by the coefficients of friction, where the coefficient of static friction ₛ is typically higher than the coefficient of kinetic or sliding friction ₖ. Since the frictional force f is the product of the coefficient of friction and the normal force N, the resulting sliding friction fₖ = ₖ N is lower than the maximum static friction fₛ = ₛ N. This physical property is why it requires less force to maintain the motion of a sliding body than to start it from a state of rest.

Show answer & explanationHide answer⌄
Answer: (A) 3D
Explanation
3D optical data storage is a technology that utilizes the volume of the storage medium instead of just the surface. While conventional optical discs like CDs, DVDs, and Blu-ray record data in one or two layers on the surface, 3D optical storage uses multiple layers throughout the thickness of the disc. By focusing a laser at different depths within the recording material, data can be addressed in three dimensions. This approach significantly increases storage capacity because it overcomes the physical limitations of surface area by exploiting the depth of the medium. It often relies on non-linear optical effects to ensure that the laser beam only interacts with the specific point in the volume being read or written, leaving the surrounding layers unaffected.

The stratosphere is the atmospheric layer situated between approximately 10 and 50 kilometers above the Earth's surface. It houses the ozone layer, which serves as a vital biological shield for the planet. Ozone molecules (O₃) in this region effectively absorb the majority of the sun's high-energy ultraviolet (UV) radiation, specifically filtering out nearly all UV-C and a significant portion of UV-B rays. By intercepting these harmful wavelengths before they reach the lower atmosphere, the stratosphere prevents them from causing cellular and DNA damage to living organisms on the surface. This absorption process also converts UV energy into heat, leading to the characteristic temperature increase with altitude found in this layer.

Answer: (B) 30%
Explanation
The total surface area of the Earth is approximately 510 million square kilometers. The land surface, which includes all continents and islands, accounts for about 149 million square kilometers of this total. By calculating the percentage as (149 / 510) × 100, the resulting value is approximately 29.2 percent. In the context of general geography and environmental science, this figure is typically rounded to 30 percent to describe the portion of the Earth's surface not covered by the hydrosphere. The remaining 70 percent to 71 percent is covered by oceans, seas, and other water bodies.

Answer: (A) Willem Einthoven
Explanation
Willem Einthoven, a Dutch physiologist, invented the first practical electrocardiogram (ECG) in 1903. He developed the string galvanometer, a device sensitive enough to record the minute electrical changes produced by the beating heart directly from the surface of the body. Einthoven assigned the letters P, Q, R, S, and T to the various deflections in the recording, establishing the standard nomenclature still used in cardiology today. His work transformed the diagnosis of cardiovascular diseases by allowing doctors to study heart rhythm and electrical conduction non-invasively. For this monumental contribution to medicine, Einthoven was awarded the Nobel Prize in Physiology or Medicine in 1924.
