amp;&& the density of a piece of cork. We weigh the cork in air, the sinker in water, then attachthe sinker to the cork and weigh them together in water. Letus suppose that the cork weighs 10 g. in air, the sinker 15 g. inwater, and that together they weigh 5 g. in water. If the cork and… … MECHANICS. LIQUIDS 45 I, Fig. 29, they weigh only 5 g. That is, the loss in weightis 20 g. Since this loss is due to the buoyant force of the wateron the cork, the cork must displace 20 c.c. of water. Thereforethe volume of the cork is 20 c.c.We can say, then: 20 c.c. of cork weighs 10 g. .. i c.c.…
