A roller-coaster car moves 161 ft horizontally and then rises 126 ft at an angle of 31.0° above the horizontal. It next travels 126 ft at an angle of 42.0° downward (below the horizontal). What is its displacement from its starting point? (Assume the initial horizontal motion of the car to be along the +x axis.)

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.

0.11 m/s and 0.28 m/s should be correct
