Aproton is moved from a position where the electric potential is 125 v to a position where the electric potential is 275 v. the magnitude of the charge on a proton is 1.602 × 10-19 c. what is the change in electric potential energy of the proton?
2.0 × 10-17 j
2.4 × 10-17 j
4.4 × 10-17 j
6.4 × 10-17 j

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.

i need the answer to this too but idk it ; -;
