Acar is travelling north at a constant speed of 20 m/s. a force is applied directly east on the car. the motion of the car will be change in which of these ways? a) the speed of the car will increase. b) the speed of the car will decrease. c) the speed will increase, and the car will change the direction it is moving. d) the speed will remain the same, but the car will change the direction it is moving.

C) The speed will increase, and the car will change the direction it is moving.

Explanation:

The car is travelling north at constant speed.  The force applied to the car is in the east direction, so it won't affect the speed in the north direction, but it will increase the speed in the east direction.  Therefore, the net speed increases, and the car changes direction.

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.
