Answer:
Explanation:
According to the conservation of momentum, when the external torque is not applied on the system, then the angular momentum of the system is conserved.
I x ω = constant
[tex]I_{1}\omega _{1}=I_{2}\omega _{2}[/tex]
where, I is the moment if inertia and ω is the angular velocity
As the star is collapsed, the radius decreases and hence the moment of inertia also decreases.
According to the law, the angular velocity increases, thus the rate of spinning increases.
