Question

WHAT WILL HAPPEN TO THE DURATION OF DAY IF THE RADIUS OF EARTH IS HALFED

Answer 1

Answer:

duration of time will be decreased

i.e. time required for 1 day will be 6hrs.

Answer 2

Answer:

I is M R^2, so since the new R is 1/2 the original, the new I must be 1/4 the original. As a result, the angular velocity must increase by a factor of 4 to conserve angular momentum.

As a result, the day will be 1/4 of 24 hours (6 hours.)
