Question

If all the ice on the polar cap of the earth melt, which of the following quantities remains
unchanged?
a Angular momentun (L)
b) Time period (T)
c) Angular velocity (w)
d) Moment of inertia (1)​

Answer 1

Explanation:

If polar ice caps will melt, water would spread on earth & so its moment of inertia would increase. But by law of conservation of momentum,speed of rotation would decrease so that angular momentum remains constant

Answer 2

Explanation:

If polar ice caps will melt, water would spread on earth & so its moment of inertia would increase. But by law of conservation of momentum,speed of rotation would decrease so that angular momentum remains constant.
