Heat energy caused by friction is usually a waste product that results when energy is destroyed or dissappears.
Friction converts useful kinetic energy into thermal energy or heat. Friction gets a bad rap for turning useful energy into useless energy.
Answer:
minimum mass of the neutron star = 1.624 × 10^30 kg
Explanation:
For a material to remain on the surface of a rapidly rotating neuron star, the magnitude oĺf the gravitational acceleration on the material must be equal to the magnitude of the centripetal acceleration of the rotating neuron star.
This can be represented by the explanations in the attached document.
