Consider a neutron star with a mass of 1.5 times that of our sun, and a radius of 15 km. Consider this to be all closely packed neutrons in a kind of fluid.
a) How does the mass density compare to the density of individual neutrons (take them to have a radius of 2.3 attometers.
b) What is the Fermi temperature and energy for this neutron star?
You have a pulley 13.1 cm in diameter and with a mass of 2.0 kg. You get to wondering whether the pulley is uniform. What is the actual moment of inertia of the pulley
