Question

explain how a metallic sphere falling through a viscous liquid attains terminal velocity.(2mks)

Answer 1

[AI-generated answer — Bot]

When a metallic sphere falls through a viscous liquid, the viscous force of the liquid acts against the sphere, slowing it down. As the sphere falls, the viscous force increases, eventually reaching a point where the force of gravity is equal to the viscous force. At this point, the sphere has reached its terminal velocity and will no longer accelerate.
