Which statement correctly applied to a spinning mobile that changes its velocity over a period of time? A. The combination of all forces acting on it is zero.

B. No net force is acting on it

C. Forces are acting on it.

D. A nonzero net force is acting on it.

forces are acting on it

Explanation:

when a body is spinning and is changing its velocity per unit, the body is said to be acted upon by forces which causes the spinning.

a body won't change in velocity unless acted by forces.

for a spinning body, a centripetal and centrifugal forces are part of those forces responsible for the spinning car and causes a shift in its velocity.
