The core of a star collapses during a supernova, forming a neutron star. Angular momentum of the core is conserved, and so the neutron star spins rapidly. If the initial core radius is and it collapses to 10.0 km, find the neutron star’s angular velocity in revolutions per second, given the Core’s angular velocity was originally 1 revolution per 30.0 days.

To determine

The neutron stars angular velocity in revolutions per seconds.

Explanation

Given info:

Radius =5 x 105

Angular velocity of core = 1 revolution per 30.0 days

Formula used:

Calculation:

The angular momentum remains conserved

L = I x ω

L = If x ωf=Ii x ωi=IiIf x ωi

Since momentum of inertiais proportional toand the angular velocity in degrees per secondis proportional to the angular frequency in revolutions per second
