A small spherical ball falling under gravity in a viscous medium heat the medium due to viscous drage force. The rate of heating is proportional to `r^(n)`. (`r=` radius of the sphere find )`n`.

A small spherical body of radius r is falling under gravity in a viscous medium. Due to friction the meduim gets heated. How does the rate of heating depends on radius of body when it attains terminal velocity?

A spherical metal ball of mass m and radius (r ) is falling through a viscous medium. The value of its terminal velocity is proportional to

A spherical metal ball of mass m and radius (r ) is falling through a viscous medium. The value of its terminal velocity is proportional to

A small sphere of radius 2 cm falls from rest in a viscous liquid. Heat is produced due to viscous force. The rate of production of heat when the sphere attains its terminal velocity is proportional to
