Explanation / Answer

(8)Due to the properties of angular momentum, the winds with the greatest velocities in a Hurricane are

(b) Located near the eye of the storm

Explanation:

According to the law of conservation of angular momentum, if the sum of all the external torques acting on an object is zero, the total angular momentum remains constant.

m v r= constant

m= mass of the object

v= velocity

r=perpendicular distance of the object from the axis of rotation

since m is constant, we can say

vr= constant

v1 r1 = v2 r2

when we move closer to the center(eye) of the hurricane, distance r decreases. So the velocity increases.

so the velocity of the winds near the eye of the storm will be greatest.
