5500
Explanation:
I cant explain it but when i asked my teacher thats what he told me
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:
<span>So we want to know what kind of wave is the scientist is studying while studying earthquakes. Waves that produce earthquakes are mechanical waves. Gamma rays and radiowaves are both electromagnetic waves and don't require a medium but mechanical do. So the correct answer is mechanical waves.</span>
