Do not answer unless you actually now how to do
a 0.20-kg stone is thrown vertically upward with an initial velocity of 7.5 m/s from a starting point 1.2 m above the ground.
(a) what is the potential energy of the stone at its maximum height relative to the ground?
(b) what is the change in the potential energy of the stone between its launch point and its maximum height?

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.

technology is the application of the knowledge gained by science.
