Question Answered step-by-step When very large stars reach the ends of their lives, their cores… When very large stars reach the ends of their lives, their cores are made of solid iron. A supernova happens when the iron core can no longer support the weight of its own gravity; it collapses into a much smaller object (of essentially the same mass) called a neutron star.Suppose that before the core collapses, it has a radius of 6000 km. During the core collapse, it shrinks to a neutron star with a radius of 50 km.In both cases, you can model it as a uniform sphere with a moment of inertia of I = 25mR2.(a) Even if the core is rotating only very slowly before it collapses, it will be rotating quickly onceit does. Explain briefly why.(b) Suppose that the neutron star rotates once every second. How quickly did the iron core rotate before it collapsed? (You can either describe its angular velocity in rotations per second, or tell me how many seconds it took to rotate before it collapsed.)
