two spheres of same size are made from copper and iron respectively. find the ratio between their masses. density of copper is 8900kg/m³ and iron is 7800kd/m³ |

Answer» Hii there, ● Answer - Mc/Mi = 1.141 ◆ Explanation - GIVEN that both spheres are of same size i.e. VI = Vc. Putting V = M / ρ, Vi = Vc Mi / ρi = Mc / ρc Mc / Mi = ρc / ρi Mc / Mi = 8900 / 7800 Mc / Mi = 1.141 Therefore, ratio of masses of copper & iron spheres is 1.141 . |
