A neutron star is an extremely dense, rapidly spinning object that results from the collapse of a massive star at the end of its life. A neutron star with 2.3 times the Sun's mass has an essentially uniform density of 4.8× 10^17 kg/m^3. Part A What's its rotational inertia? Assume the star is a solid sphere. Express your answer with the appropriate units. Part B The neutron star's spin rate slowly decreases as a result of torque associated with magnetic...
