As a huge rotating cloud of particles in space gravitate together forming an increasingly dense ball, it shrinks in size and
A)rotates slower.
B)rotates at the same speed.
C)rotates faster.
D)cannot rotate.

Question

Quizplus · Accepted Answer

As the cloud of particles shrinks, the conservation of angular momentum causes it to rotate faster. This is similar to how an ice skater can spin faster by pulling in their arms, reducing their rotational radius. Therefore, the correct answer is choice C, rotates faster.
