Question

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 1

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 .

Thanks for asking. Hope I was helpful..

Answer 2

Answer:

Mc/Mi = 1.141

Explanation:

Given that both spheres are of the 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.
