(a) Explanation Given info: The mass of the earth is 5.97 × 10 24 kg and the radius of the earth is 6.37 × 10 6 m (from appendix F) Formula to calculate the density of the earth is, ρ = m V ρ is the density of the earth. m is the mass of the earth. V is the volume of the earth. Formula to calculate the volume of the earth is, V = 4 3 π r 3 r is the radius of the earth. Substitute 4 3 π r 3 for V to find ρ . ρ = 3 m 4 π r 3 Substitute 5.97 × 10 24 kg for m and 6 (b) To determine The density of the sun after five billion year. (c) To determine The density of typical neutron star.
