Neutron stars consist only of neutrons and have unbelievably high densities. A typical mass and radius for a neutron star might be 4.1 x 1028 kg and 1.4 x 103 m. (a) Find the density of such a star. (b) If a dime (V = 2.0 x 10-7 m3) were made from this material, how much would it weight (in pounds)?
Homework Answers
m = 4.1*10^28 kg, R = 1.4*10^3 m
(a) density = mass/volume
d = 4.1*10^28/((4/3)*3.14*(1.4*10^3)^3)
d = 3.57 *10^18 kg/m^3
(b) V = 2*10^-7 m^3
w = mg = d*V*g
w = 3.57*10^18*2*10^-7*9.8
w = 7*10^12 N
w = 1.574*10^12 lbs

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 1.75 103 m and 2.90 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.) lb

2) Densities We discussed White Dwarfs and Neutron stars, very dense objects compared to stars like our sun. On the other hand, we also discussed Red Giants which are much less dense than our sun. To realize just how dense, please compute the average densities (in kg/m) for a) the sun (Rsun=7 x 10 km, Msun= 2 x 1030 kg) b) when the sun becomes a red giant (R= 1AU, M=Msun). By what factor is a Red Giant less dense...

Neutron stars are created when giant stars die in supernovas and their remaining cores collapse to a state of immense density where protons and electrons combine to form neutrons. A neutron star is ~1.4 times as massive as the sun and has radius of only ~10 km. For this neutron star compute its escape velocity. What percentage of the speed of light does this correspond to? (Assume for the mass of the sun, M = 1.989 x 10^30 kg).
