When the two balls hit each other what will happen if it’s perfectly inelastic collision

A ball sticking to the wall is a perfectly inelastic collision. – The velocity of the ball after the collision is zero. – Its kinetic energy is then zero. – All of the kinetic energy has been lost.

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
