if the earth were to shrink suddenly,what will happen to the length of the day

Expert Answer:

If the earth were to shrink its speed would increase. This can be shown using conservation of angular momentum.

This is similar to the increase in speed of a dancer who initially has her hands stretched out and then draws them in.

If the earth rotates faster, the duration of a day decreases.
