A small sphere of radius falls from rest in a viscous liquid. As a result, heat is produced due to viscous force. The rate of production of heat when the sphere attains its terminal velocity is proportional to
To solve this problem, we need to understand the relationship between the viscous force, terminal velocity, and heat production.When a small sphere falls through a viscous liquid, it experiences a viscous force given by Stokes' law:where
