Question
Suppose a neutron star is spinning with a period of 1.000 sec. If its radius shrinks by $1 \%$, what will its new period be?
Step 1
First, we need to understand the concept of conservation of angular momentum. The angular momentum of a rotating object is given by the product of its moment of inertia (I) and its angular velocity (ω): L = Iω. When an object's shape changes but no external Show more…
