Is the displacement of an object during a specific unit of time.

The answer is Velocity

Explanation:

The displacement of an object during a specific amount of time is speed. For example, Marsha ran 5 meters in 20 minutes. Divide 5 meters by 20 minutes and you will get ¼ meters per minute. Or if you want a unit of m/s, changing 20 minutes into seconds and you will get 1200 seconds. Then divide 5 by 1200 and you will get 1/240 m/s. 

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.

a, c, d, e are all applying about success strategies.
