Since neutron stars consist totally of neutrons, they are extremely massive and have a density that is hard to imagine. A typical radius and mass for a neutron star are 1.95  103 m and 2.60  1028 kg respectively. (a) Determine the density of a neutron star.   kg/m3 (b) Determine the weight (in pounds) of a penny (V = 360 mm3) if it were made from this material. (Assume 1 lb = 4.448 N.)
