When a large star becomes a supernova its core may be, Ask an Expert

Academics

When a large star becomes a supernova, its core may be compressed so tightly that it becomes a neutron star, with a radius of 20 km (about the size of San Francisco). If a neutron star rotates once every second, (a) what is the speed of a particle on the star’s equator? (b) What is the magnitude of the particle’s centripetal acceleration? (c) If the neutron star rotates faster, do the answers to (a) and (b) increase, decrease, or remain the same?
