Two cars start a race with initial velocity 7ms-1 and 4ms-1 respectively. their acceleration are 0.4ms-2 and 0.5ms-2 respectively. if the two cars finish the race at the same time, what is the distance of the track?

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.

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.
