How does a coronal mass ejection (cme) affect the solar wind? a. a cme adds more particles to the solar wind, intensifying it. b. a cme does not affect the solar wind but it does affect auroras. c. a cme blocks the solar wind, causing it to fade. d. a cme increases the amount of energy in the solar wind.

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.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer
