If Earth's moon were replaced by a neutron star with a radius of 13 km, what would the angular diameter of the neutron star be as seen from Earth? (Hint: Use the small-angle formula, angular diameter (in arc seconds) / 2.06 ✕ 105 arc seconds = linear diameter/distance, where the linear diameter and the distance both have the same units.)
A certain giant molecular cloud has a mass of 9.50 x 1035 kg, and 2.00 percent of its mass is converted into stars during a single encounter with a shock wave. How many stars can it make if you assume that the stars have an average the mass of 3.0 x 1030 kg?
Assume a neutron star has a mass of about 1.2 times the mass of the Sun and a radius of 7 kilometers. a) Calculate the average density of a neutron star, in kilograms per cubic centimeter.
