Answer 1

Answer:

Angular momentum is conserved, so that: For a solid sphere, So planet Earth would rotate about four times in 24 hours, reducing our day length to six hours. ... If the Earth somehow expanded to a large radius with no change in mass, how would your weight be affected?

Answer 2

Answer:

If you mean that the mass gets sliced off, then the length of the day depends on whether the sliced-off parts take any of the angular momentum with them.
