Question

What is the specific gravity of the

metal, if the piece of metal weighs 150

grams in air and 125 grams in water? |​

Answer 1

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)
