A20.0kg cart travels at 10.0 m/s in a circle with a radius of 15.0 m. what is the centripetal force?

Centripetal force, F = 133.34 N

Explanation:

It is given that,

Mass of an object, m = 20 kg

Radius of circle, r = 15 m

Velocity of the object, v = 10 m/s

We have to find the centripetal force of the cart. The centripetal force is given by :

F = 133.34 N

Hence, the centripetal force acting on the object is 133.34 N

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.
