One of the two clocks on the earth is controlled by a pendulum and other by a spring. If both the clocks are taken to the moon, then which clock will have same time period as that on the earth?

In the following question, a Statement of Assertion (A) is given followed by a corresponding Reason (R) just below it. Read the Statements carefully and mark the correct answer-
Assertion(A): When light goes from a medium of refraction index 1.5 to a medium of refraction index, 1.6, its speed decreases by 1.875 * 10⁸ m/s.
Reason(R): Refraction index = speed of light in vacuum speed of light in air

In the following question, a Statement of Assertion (A) is given followed by a corresponding Reason (R) just below it. Read the Statements carefully and mark the correct answer-
Assertion(A): A steady current flows in a metallic coductor of non-uniform cross-section. Only drift a speed remains constant along the length of the conductor.
Reason(R): vs = one A (symbols have their usual meaning).

In the following question, a Statement of Assertion (A) is given followed by a corresponding Reason (R) just below it. Read the Statements carefully and mark the correct answer-
Assertion(A): Nuclei having number about 60 are most stable.
Reason(R): When two or more light nuclei are combined into a heavier nucleus, then the binding energy per nucleon will increase.

In the following question, a Statement of Assertion (A) is given followed by a corresponding Reason (R) just below it. Read the Statements carefully and mark the correct answer-
Assertion(A): Pendulum of a clock is made of alloys and not of pure metals.
Reason(R): Use of alloys make the pendulum look good.
