A metal sphere of radius r and specific heat s is rotated about an axis passing through its centre at a speed of n rotation/s. It is suddenly stopped and `50%` of its energy is used in increasing its temperature. Then, the rise in temperature of the sphere is

A metal sphere of radius R and specific heat C is rotated about an axis passing through its centre at a speed n rotation/second. It is suddenly stopped and 50% of its energy is used in increasing its temperature, then find the rise in temperature of the sphere

A metal sphere of radius r and specific heat s is rotated about an axis passing through its centre at a speed of n rotations per second. It is suddenly stopped and 50% of its energy is used in increasing its temperature. Prove that the raise in temperature of the sphere is (2pi^(2)n^(2)r^(2))/(5s) .
