Ga parallel-polarized electromagnetic wave impinges from medium 1 (µ1 = µ0, ε1 = 81ε0) to medium 2 (µ2 = µ0, ε2 = ε0).

(a) what is the critical angle?

(b) what is the brewster angle?

(c) if the incident angle is 60˚, find the reflection coefficient | ii| and the phase angle arg(ii)

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.

i think the answer is a, hope this is right, that would be my best guess.

grav forces affect all objects magnetic forces affect magnetic objects and electric currents
