Answer:
Explanation:
During this process the mass 
will be considered constant. We start from a radius 
and a period 
. The final period is 
.
Angular momentum <em>L</em> is conserved in this process. We can use the formula 
, where I is the momentum of inertia (which for a solid sphere is 
) and 
is the angular velocity, so we can write the star's angular momentum as:
Since 
we have:
Which can be simplified as:
Which means:
Which for our values is:
And we calculate the speed of a point on the equator by dividing the final circumference over the final period:
The answer is : 35 to 52 minutes.

The voltage in AC circuits also periodically reverses because the </span>current<span> changes direction. So my answer is A.</span>
