The jets of material moving away from a supermassive black hole are generated by high pressures and temperatures at the base of the accretion disk.What causes these high pressures and temperatures?

Question

Quizplus · Accepted Answer

Friction within the accretion disk generates heat, causing the disk to reach high temperatures and pressures at the base of the disk. This heat also causes gas in the disk to ionize, creating a plasma that produces the jets of material moving away from the black hole. Therefore, the correct answer is friction (choice B). Radioactivity (choice A) and fusion (choices C and D) do not play a significant role in generating the high temperatures and pressures within the accretion disk.
