Imagine that you have a solid cube of Material X. You have a beaker filled to the brim with pure water. The water-filled beaker is resting on a scale. You now slowly lower the cube of Material X into the beaker. It sinks to rest on the bottom and some water is displaced from the beaker. Material X is completely immersed in the water and the displaced water runs off the scale. Which, if any, of the following statements is/are true?
Choices: True, False. � The density of Material X must be greater than that of
pure water.
� The normal force exerted by the bottom of the beaker on the cube is less than the weight (in air) of the cube.
� The cube of Material X weighs the same as a cube of water the same size.
� The scale reads the weight of the water remaining in the beaker, the weight of the beaker, and the weight of Material X.
� There is no buoyant force acting on the cube of Material X.
� The buoyant force on Material X is equal to its own weight.
� The cube displaces an amount of water equal to its own weight.
� The weight of displaced water equals the weight of Ma- terial X.
