B) 1/2000 second.
C) 8 minutes.
D) a few hours.

Question

Quizplus · Accepted Answer

During the process of core collapse in a massive star, the time taken from the start of collapse to the attainment of nuclear density is very short, on the order of fractions of a second. The collapse is very rapid and leads to a supernova explosion. Option A) 1/4 second is the best choice as it falls within this time frame. B) 1/2000 second, C) 8 minutes, and D) a few hours are all much longer than the actual time taken for core collapse.
