Which of the following is NOT a form of kinetic friction? O fluid friction
O slipperiness
O rolling friction
O sliding friction

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 believe the answer is electric potential.

explanation:

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.

snell's law

refractve index = sin incidence / sin refraction
