ok, so i had a test today and me and my friends are debating the answer. The question is: A peice of metal is resting on top of a floating peice of wood in a tub of water. If the metal is removed from the peice of wood, what happens to the water level of the tub?
It stays the same?
It goes down?
or You cant tell from the info given?

It goes down!
As you remove the metal the block of wood will float up displacing less water and the level of water will go down.

The piece of floating wood is displacing an amount of water. What ever type of metal is on the wood, it still weights something, so the piece of wood is now lighter, therefore displacing less water. The level of water in the tank would go down. Wood goes up, water level goes down.

The metal displaces its MASS of water. Since the metal is denser than water, when it is removed, the wood rises up, the displacement is less, and the level of water goes down.
