Planet x has nine times the diameter and three times the mass of the earth. what is the ratio gx : ge of gravitational acceleration at the surface of planet x to the gravitational acceleration at the surface of the earth?

this a false

explanation:

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.
