One of the end stages of stellar life is a neutron star, where matter collapses and electrons combine with protons to form neutrons. Some liken neutron stars to a single gigantic nucleus. Calculate the radius in meters of a neutron star with a mass 2.96 x 1030 kg, treating it as a giant nucleus. Consider the mass of a nucleon 1.675 x 10-27 kg. Your answer should be in the form of N x 104 years. Enter only the number...
Calculate the density of a neutron star with a radius 1.34 x 104 m, assuming the mass is distributed uniformly. Treat the neutron star as a giant nucleus and consider the mass of a nucleon 1.675 x 10-27 kg. Your answer should be in the form of N x 1017 kg/m3. Enter only the number N with two decimal places, do not enter unit.
Calculate the density of a neutron star with a radius 1.69 x 10^4 m, assuming the mass is distributed uniformly. Treat the neutron star as a giant nucleus and consider the mass of a nucleon 1.675 x 10^-27 kg. Your answer should be in the form of N x 10^17 kg/m3. Enter only the number N with two decimal places, do not enter unit.
At the end of its life, a star with a mass 5.8 times the Sun's mass is expected to collapse, combining its protons and electrons to form a neutron star. Such a star could be thought of as a gigantic atomic nucleus. If a star of mass 5.8 x 1.99 x 1030 kg collapsed into neutrons (mn = 1.67 x 10-27 kg), what would its radius be? Assume that r = r0A1/3.
Neutron stars are created when giant stars die in supernovas and their remaining cores collapse to a state of immense density where protons and electrons combine to form neutrons. A neutron star is ~1.4 times as massive as the sun and has radius of only ~10 km. For this neutron star compute its escape velocity. What percentage of the speed of light does this correspond to? (Assume for the mass of the sun, M = 1.989 x 10^30 kg).

Select one: a. It will cool down and become a cold black dwarf. b. As gravity overwhelms the electron degeneracy pressure, it will explode as a nova. c. As gravity overwhelms the electron...
