What happens to the gravitational energy of gas as it falls toward and eventually hits the accretion disk surrounding a protostar?
A) It is converted into thermal energy, heating the disk.
B) It is converted into light energy, giving off a flash of light upon impact.
C) It is converted into potential energy as the gas plows through the disk and comes out the other side.
D) It simply dissipates.
