Awheel with the rotational inertia i, mass m, and a radius r is attached to a wall with a horizontal spring with elasticity k. assuming the wheel rolls on horizontal surface without friction, calculate the frequency of harmonic oscillations.

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.
