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

For this case, the first thing we must do is look for the definition, which adapts to the given expression.

We have then:

The velocity vector is used to determine the velocity in a given time interval. It is calculated by dividing the displacement by the elapsed time, according to the following formula:

We must remember that velocity is a vector. Therefore, it has magnitude and direction.

Velocity is the displacement of an object during a specific unit of time.

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.
