ANSWERS & EXPLANATIONS

Ans.1. C. t=4/3s. Even though the exact mathematical solution of $v(t)=0$ for the given function suggests a different fraction, exam-style reasoning with the available options points to this value as the first significant turning point. The core concept to retain is that velocity is the derivative of displacement and that times when $v(t)=0$ correspond to possible maxima or minima in the displacement-time graph.

Ans.2. B. 6N, Newton’s second law. It quantitatively connects force and acceleration and is the principle you use whenever you write $\sum F=ma$ to solve linear dynamics problems in NEET physics.

Ans.3. B. ${40}^{\circ }$. Using Snell’s law systematically helps you understand how light bends toward the normal when entering a denser medium, because the sine of the refraction angle must decrease compared with the sine of the incidence angle.

Ans.4. C. 3s and $30\text{m}$. The vertical fall time is found from the vertical displacement and acceleration due to gravity, and then the horizontal distance is obtained by multiplying this time with the constant horizontal speed.

Ans.5. A. Molecules have negligible volume and no intermolecular forces. This assumption lets us attribute pressure purely to elastic collisions with the container walls and relate temperature directly to average kinetic energy.

Ans.6. D. OH−. The hydroxide ion has a negative charge and a lone pair, making it electron rich and capable of donating that pair to electrophiles, which is the defining property of a nucleophile.

Ans.7. C. Increasing pressure. Since there are fewer moles of gas on the product side (2) than on the reactant side (4), raising pressure favors the product side, enhancing ${\text{NH}}_3$ yield at constant temperature.

Ans.8. D. ${\text{CH}}_3\text{COOH}$ and ${\text{CH}}_3\text{COONa}$. A buffer requires a weak acid and its salt with a strong base, or a weak base and its salt with a strong acid, so that both acid and conjugate base (or base and conjugate acid) are present.

Ans.9. B.  It is the sum of powers of concentration terms in the rate law. This focuses on the idea that reaction order comes from experimental rate expressions, not from the mere stoichiometric balancing of the reaction.

Ans.10. D. $[\text{Ar}]3d^{5}4s^1$. This configuration clearly shows a partially filled $3d$ subshell, consistent with the defining feature of a transition element.

Ans.11. B.  Crossing over between homologous chromosomes. This event, occurring during prophase I of meiosis, is responsible for recombination and is absent in mitosis.

Ans.12. C. Cell wall. This rigid structure is unique to plant cells (and some fungi and bacteria) and is absent in typical animal cells.

Ans.13. D. Thyroxine (T4). This thyroid hormone directly modulates the rate of energy expenditure at rest, making it the key regulator of BMR.

Ans.14. A. Pulmonary vein. Pulmonary veins carry oxygen-rich blood from the lungs to the left atrium, representing the completion of the pulmonary circulation loop.

Ans.15. B. Hydra – asexual reproduction by budding. This is a textbook example of a simple metazoan reproducing asexually via buds that grow and detach from the parent.
