One cubic meter (1.00 m) of aluminum has a mass of 2.70 10 kg, and the same volume of iron has a mass of 7.8610'kg. find the radus of a solid aluminum sphere that will balance a sod irn sphere o radu 14 squal-a balano rm

The radius of the solid aluminum sphere has to be

Explanation:

Hi

First of all, we're going to find the density of both materials, to do that we use ρ. Then and .

the second step is to find Volume of the iron sphere () so, .

The third step is to find the mass () on this iron sphere so,

The fourth step, we are going to use to find aluminum Volume hence its radius, , as we clear we find that, , then.

think its the third option

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.
