Therefore,

ratio of masses of copper & iron spheres is 1.141.

Hope this answer helps you!!!

Answer 2

Answer:

Let volume be 1 m³.

∴ Mass of copper sphere = 8,900 kg/m³ ÷ 1 m³.

                              => 8,900 kg.

∴ Mass of iron sphere = 7,800 kg/m³ ÷ 1 m³.

                                     = 7,800 kg.

∴ Ratio is copper : iron = 8,900 : 7,800         [8900 kg / 7800 kg]

                                      = 89 : 78.

Hence, answer = 89 : 78.
