A14.0 kg iron mass rests on the bottom of a pool. (the density of iron is 7.86 ✕ 103 kg/m3 and the density of water is 1.00 ✕ 103 kg/m3.) hint (a) what is the volume of the iron (in m3)? m3 (b) what buoyant force acts on the iron (in n)? (enter the magnitude.) n (c) find the iron's weight (in n). (enter the magnitude.) n (d) what is the normal force acting on the iron (in n)? (enter the magnitude.) n
