GK Test 15 (Static)

When the ball is thrown vertically upward in a car moving at constant velocity, it retains the horizontal velocity of the car (Galilean relativity). The ball and the thrower continue moving forward together at the same speed, so the ball falls back into the thrower's hands. Air resistance would change this outcome, but the problem states it's neglected. This is the same principle that allows passengers to toss objects in a moving train or airplane.

Enterokinase (also called enteropeptidase) is a protease enzyme produced in the duodenum. Its primary and most important function is to activate trypsinogen (the inactive precursor) into trypsin by cleaving off an activation peptide. Trypsin then activates other pancreatic zymogens (procarboxypeptidase, chymotrypsinogen, etc.) creating a digestive enzyme cascade. Options A, B, and C describe functions of other enzymes.

The Chitnis in Shivaji's administration was responsible for managing the king's official correspondence and documentation. This included drafting letters, maintaining records of diplomatic communications, and handling administrative paperwork. The role was crucial for governance as Shivaji corresponded with other rulers, managed alliances, and issued administrative orders. Option A describes the personal guards (not Chitnis), B refers to intelligence officers (like the Bahirjee Naik), and C is the role of the Sabhasad.

Asteroids are small rocky bodies that orbit the Sun, primarily found in the asteroid belt between Mars and Jupiter. They are much smaller than planets - most are irregularly shaped and range from boulders to objects nearly 1000 km in diameter. Comets are icy bodies that develop tails when near the Sun, meteors are shooting stars (atmospheric phenomena), and meteorites are meteors that reach Earth's surface.

Cyathium is the correct answer. It's a specialized inflorescence found in Euphorbia species, characterized by a cup-shaped involucre (the cyathium) that contains a single central female flower (pistillate) surrounded by several male flowers (staminate) on short stalks. Capitulum is a flower head (like sunflower), Hypanthodium is a fleshy receptacle (like fig), and Verticillaster is a whorled inflorescence (like in Ocimum).

Cnidarians (jellyfish, sea anemones) have a simple body organization without a true coelom, making them acoelomate. Some sponges like Spongilla inhabit freshwater, so not all are marine. Flatworms can reproduce asexually through transverse fission. Many arthropods like crustaceans have external fertilization where eggs are released into water.

Annapurna Scheme was launched in April 2000 to provide food security to senior citizens (65 years and above) who were not covered under the National Old Age Pension Scheme. It provided 10 kg of free food grains per month to eligible beneficiaries.

Benzene undergoes electrophilic aromatic substitution with chlorine in the presence of iron(III) chloride catalyst (Fe acts as Lewis acid, FeCl3 is the actual catalyst). This produces chlorobenzene where a chlorine atom substitutes for a hydrogen atom on the benzene ring.

Article 164(1)(b) caps State Legislative Assembly membership at 500 (or fewer as specified by law). The minimum age for MLA membership is 25 years (Article 173). The Legislative Council cannot exceed one-third of Assembly strength, not half. The Council Chairman is elected by Council members, not nominated by Governor.

Article 108 of the Constitution states that when a Bill is referred to a joint sitting (for resolving deadlock between Lok Sabha and Rajya Sabha), it is passed by a simple majority of members present and voting. Special majorities are not required for joint sitting decisions.

Yoweri Kaguta Museveni has been the President of Uganda since 1986, making him one of Africa's longest-serving leaders. He came to power after the bush war that toppled Milton Obote's government and Tito Okello's military regime.

The Charter Act of 1833 completely ended the East India Company's commercial trade monopoly in India, allowing all British merchants to trade freely. Earlier Acts like 1813 had only partially opened trade to other merchants in specific areas.

Bile salts are derived from cholesterol and have a steroid nucleus structure (cyclopentanoperhydrophenanthrene ring system). Lipases are water-soluble enzymes. Trypsin is a pancreatic enzyme that works best in alkaline pH of small intestine. Pepsin is denatured by the alkaline environment of duodenum.

India ranks 7th globally by total area (~3.29 million sq km) and is the largest among the given options. Argentina is ~2.78 million sq km, Kazakhstan is ~2.72 million sq km, and Sudan is ~1.88 million sq km. India is approximately one-third the size of the largest country (Russia).

For rolling without slipping, acceleration depends on moment of inertia: a = gsin(θ) / (1 + I/mr²). Sphere has lowest I (2/5 MR²), giving highest acceleration ~0.714gsin(θ). Disc has I = 1/2 MR² (acceleration ~0.667gsin(θ)). Ring has highest I = MR² (acceleration ~0.5gsin(θ)). Sphere reaches bottom first.

Louis Pasteur disproved the theory of spontaneous generation in 1859 using his famous swan-neck flask experiment. He showed that microorganisms only appeared in broths when exposed to air containing dust particles, not from spontaneous generation from non-living matter.

All four substances listed are vitamins. Ascorbic acid is Vitamin C, folic acid is Vitamin B9, nicotinic acid (niacin) is Vitamin B3, and pantothenic acid is Vitamin B5.

Aspergillus is a genus of fungi, while the other three options are all bacteria. Staphylococcus and Clostridium are genera of bacteria, and Salmonella is a bacterial genus as well.

She answered 40 problems correctly (7 arithmetic + 12 algebra + 21 geometry). To pass at 60%, she needs 45 correct answers (60% of 75 = 45). The difference is 5 more questions needed.

Bahadur Shah Zafar was the last Mughal emperor. Similarly, Ibrahim Lodi was the last ruler of the Lodi dynasty, who was defeated at the First Battle of Panipat in 1526.

The National Environment Tribunal Act was enacted in 1995. The other acts listed were enacted in different years: Environment (Protection) Act in 1986, Forest (Conservation) Act in 1980, and Wildlife (Protection) Act in 1972.

Specific heat capacity is the amount of heat required to raise the temperature of a substance by 1 degree. If A heats up more than B with the same heat, A must have lower specific heat capacity (Q = mcΔT).

Statement 2 is correct because atmospheric pressure decreases with altitude as the air column becomes shorter. Statement 3 is correct because continents cool faster than oceans in winter, creating high pressure zones. Statements 1 and 4 are incorrect.
