A particle at the origin starts motion from rest along the x axis with acceleration a = 6t2, where a is in m/s? andt is in seconds. The average velocity of the particle as it travels from x-8m to x = 128 m is:

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.
