A) What parts of the EM spectrum are being used? Compare them in terms of wavelength, frequency, and energy.

All?

Explanation:

As wavelengths get shorter, energy increases, and frequency increases. As wavelenghts get longer, energy decreases, and frequency decreases. We can see the visible spectrum where the side UV has the shortest and strongest waves, but the IR side has the longest and weakest wavelengths.

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.
