To determine the composition of a bimetallic alloy, a sample is first weighed in air and then in water. These weights are found to be w1 and w2 respectively. If the densities of the two constituent metals are ρ1 and ρ2 respectively, then the weight of the first metal in the sample is (where ρw is the density of water)

A uniform rod is suspended horizontally from its mid-point. A piece of metal whose weight is w is suspended at a distance l from the mid point. Another weight W1 is suspended on the other side at a distance l1 from the mid-point to bring the rod to a horizontal position. When w is completely immersed in water, w1 needs to be kept at a distance l2 from the mid-point to get the rod back into horizontal position. The specific gravity of the metal piece is
