Question

1. Neutron stars consist only of neutrons and haveunbelievably high densities. A typical mass and radius for aneutron star might be 4.8 x 1028 kg and 1.5 x103 m. (a) Find the density of such astar. (b) If a dime (V = 2.0 x10-7 m3) were made from this material, howmuch would it weight (in pounds)? solve it with answer please. 1.

Explanation / Answer

Tested answer, got this earlier this week: Density is equal to mass over volume so: =m/V Where V = 4/3**r3 a) = 4.8 x 1028 kg/ (4/3**(1.5 x103 m)^3) = 6.036 x 1018 kg/m3 or6,036,000,000,000,000,000 kg/m3 b) m = /V m = (6.036 x 1018 kg/m3)/( 2.0 x10-7 m3) m = 3.018 x 1025 kg or30,180,000,000,000,000,000,000,000 kg
