Archimedes explored the density concept rather extensively, and developed the buyouncy principle. Buoyoncy can be simply expressed as "the buyount force is equal to the weight of fluid displaced." In other words, and object will sink until it has displaced a mass of fluid equal to its own mass. A certain cork with a volume of 28 cm^3 and mass of 5.00 grams is placed in a pan of water.
1. Will it sink or float? Why?
2. At equilibrium, what mass of water is displaced?
3. At equilibrium, what volume of water is displaced?
4. What volume of the cork will be under water?
