Neutron stars consist only of neutrons and have unbelievably high densities. A typical mass and radius for a neutron star might be 2.7 × 10-8 kg and 1.2 × 103 m.
(a) Find the density of such a star.
(b) If a dime (V = 2.0 × 10-7 m3) were made from this material, how much would it weigh (in pounds)?
