Statement-1 : When ice on polar caps of ...

Statement-1 : When ice on polar caps of earth melts, duration of the day increases.
Statement-2 : `L = I omega = I ((2pi)/(T)) = constant`.

A

Statement-1 is true, Statement-2 is true ,
Statement-2 is correct explanation of Statement-1.

B

Statement-1 is true, Statement-2 is true but Statement-2 is not correct explanation of Statement-1.

C

Statement-1 is true, but statement-2 is false.

D

Statement-1 is false, but statement-2 is true.

Text Solution

Verified by Experts

The correct Answer is:
A
Both the statements are true and statement-2 is a correct explanation of statement-1. Infact, as ice on polar caps of earth melts, mass near the polar axis spreads out, Moment of inertia `I` increases. Therefore, `T` increases i.e. duration of the day increases.
