ANSWERS & EXPLANATIONS

Ans.1. C. It depends only on h. The ball has two independent components of motion: horizontal (with constant velocity u) and vertical (freely falling under gravity g). The time of flight is simply the time taken to fall from height h to the ground, which is found using the vertical motion equation $h=\frac{1}{2}g{t}^2$.

Ans. 2. A. Virtual, erect, and enlarged. When the object lies between the lens and its principal focus F, incident rays from the object diverge after refraction by the lens. The refracted rays do not actually meet but appear to come from a point behind the object when traced backwards. Since no actual convergence occurs, the image is virtual and cannot be obtained on a screen. 

Ans.3. A. They have delocalized electrons that move freely throughout the lattice. In metallic bonding, metal atoms release some of their valence electrons to form a “sea” of delocalized electrons that are not confined to any particular atom. These electrons can move under the influence of an applied electric field, creating an electric current. The positive metal ions remain in an ordered lattice, but the mobile electrons are the actual charge carriers.

Ans.4. D. Moving with constant speed in the negative direction. Acceleration corresponds to a change in velocity over time. On a displacement–time graph, this appears as a change in slope, giving a curved line. A straight line, whether sloping up or down, indicates constant velocity (zero acceleration). A negative slope specifically indicates motion in the negative direction. 

Ans.5. A. They are formed by doping silicon with trivalent impurities. Pure semiconductors have limited conductivity, but doping with appropriate impurities dramatically increases it. In p-type material, the presence of many holes allows electric current to flow when a potential difference is applied. 

Ans.6. D. It increases the kinetic energy and effective collisions of substrate molecules. Enzymes provide an alternate reaction pathway with lower activation energy by binding substrates at their active sites and stabilizing the transition state. When temperature is raised slightly (below the denaturation point), both enzyme and substrate molecules move faster. Increased kinetic energy means more molecules possess enough energy to reach the transition state and there are more frequent productive collisions between enzyme and substrate.

Ans.7. C. +600. This value is the work associated with the system in thermodynamic sign convention (work done by the system is negative). However, when a gas expands, it pushes the surroundings and does positive work on them. 

Ans.8. C. MgCl${}_2$. For colligative properties, the key factor is the number of solute particles. 

Ans.9. A. 2-Butene. For cis–trans isomerism in alkenes, a $\text{C}=\text{C}$C=C bond with different substituents on each carbon is necessary. 2-Butene has this arrangement and can exist as cis and trans forms.

Ans.10. B. Internal energy remains constant. In an isothermal process, the temperature of the gas remains fixed. For an ideal gas, the internal energy is a function of temperature alone, often written as $U=n{C}_{v}T$. Since $T$ is constant, $U$ stays constant as well. 

Ans.11. C. Stratified squamous epithelium – protection against mechanical stress. Ciliated epithelium has hair-like structures called cilia on its free surface. In the respiratory tract, cilia beat rhythmically to move mucus and trapped particles upward, helping clean the airways. In the fallopian tubes, cilia help transport the ovum. Fat storage is actually a function of adipose tissue, a type of connective tissue, not an epithelial type. 

Ans.12. A.

Ans.13. B. Rise in ventricular pressure above atrial pressure. During the cardiac cycle, when the ventricles begin to contract (ventricular systole), the pressure inside the ventricles rapidly increases. As soon as ventricular pressure becomes higher than the pressure in the atria, the pressure gradient forces the atrioventricular valves (tricuspid on the right and bicuspid/mitral on the left) to snap shut.

Ans.14. C. Aldosterone – increases reabsorption of Na${}^{+}$ in kidney tubules. ADH, secreted by the posterior pituitary, acts on the collecting ducts to make them more permeable to water by increasing aquaporin channels. This enhances water reabsorption, concentrating the urine.

Ans.15. D. It is non-overlapping and unambiguous. With four possible bases and triplet codons, there are $4^3=64$ possible codons, sufficient to encode 20 amino acids and stop signals.
