Answer» Explanation: What is the specific gravity of the metal when it weighs 45N in the air & 28.3N when FULLY submerged in water? S.G. = weight (or mass) of object / weight (or mass) of same vol of water. Buoyancy = weight of this DISPLACED water = 16.7 N SG = 45/16.7 (I’d guess an aluminium ALLOY) |
