A single star in the process of forming starts by spinning slowly (while it is quite large and relatively cool.) As the star collapses under the pull of its own gravity, its size decreases. As a result, its rate of spinning:_____.

Answer :

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.
