3. A particle of mass 1.0 MeV/c2 and kinetic energy 2.0 MeV collides with a stationary particle of mass 2.0 MeV/c2. After the collision, the particles stick together. Find: a. the speed of the first particle before the collision, b. the total energy of the first particle before the collision, c. the initial total momentum of the system.

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.
