Suppose a comet has an orbital period of 309.1 years around the sun. what is it’s average distance from the sun?

As we know from kepler's law that

here we know that for earth we have time period T = 1 year and its average distance from Sun is 1 AU

so here from above equation we have

from above equation we have

as we also know that

so average distance will be

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.
