PLZ I NEED HELP. :(

The diagram shows an inclined plane.

What is the mechanical advantage of the inclined plane?

A) 0.25

B) 4

C)90

D) 150

Option B). is the correct choice.

Explanation:

The mechanical advantage is the ratio of an input force to an output force. To calculate the ideal mechanical advantage for an inclined plane, divide the length of the incline by the height of the incline.

Mechanical Advantage  

im not to sure what it is

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.
