Imagine you and a loarge rock are in a rowboat floating at the centre of a small pond. without capsizing the rowboat, you lift the rock and drop it into the water, and then watch as it sinks to the bottom of the pond. assuming the depth of water int the pind could be measured, explain in complete detail ( using mathematical and diagrammatical support) the relationship between the depth of the water when the rock was in the rowboat and the depth of the water after the rock has sunk to the bottom.
