Massive stars can become neutron stars, pulsars, or black holes.

Pulsars, first discovered in 1967, are rotating neutron stars. The name pulsar comes from the fact that these neutron stars seem to pulse due to their rotation. Over the last decades, all BUT one type of electromagnetic wave has been used to detect and track pulsars. That isResponsesA X rays.X rays.B UV waves.UV waves.C radio waves.radio waves.D gamma waves.

he weight of a star is usually balanced by two forces: the gravitational force, acting inward, and the force created by nuclear reaction, acting outward. Over a long period of time, the force due to nuclear reactions gets weaker, causing the gravitational collapse of the star and crushing atoms out of existence. Under such extreme conditions, protons and electrons are squeezed to form neutrons, giving birth to a neutron star. Neutron stars are massively heavy-a teaspoon of the substance of a neutron star would weigh 100 million metric tons on the Earth.  Consider a neutron star whose mass is twice the mass of the Sun and whose radius is 12.1 km. (The mass of the Sun is 1.99 ⋅ 1030 kg1.99 · 1030 kg ) If it rotates with a period of 1.73 s, what is the speed of a point on the Equator of this star?
