Mobile phones use electromagnetic waves in the wavelength range that includes short wave radio wave and microwaves. Describe the effect on mobile phone users if remote control handsets operate on this range as well

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.

pe = weightxheight = 2000x1000=2,000,000joules

t = 1/400 h   ⇔ 0.0025 h ⇔ 9s ⇔ 0.15 m

any of the answers are correct.
