A piece of wax wieghs 18.03 g in air. A piece of metal is found to weigh 17.03 g in water. It is tied to the wax and both together weigh 15.23 g in water. Then, the specific gravity of wax is

A piece of wood weights 40gxxg in air. A piece of brass of mass 12 g is tied to the wooden piece and the combination floats just totally immersed in water. If the specific gravity of brass is 8.5, calculate the specific gravity of wood. [Density of water = 1g*cm^(-3) ]

A body weighs 160g in air 130 g in water and 136g in oil what is the sspecific gravity of oil?
