A cubical block of wood 0.100 m on a side and with density of 550 kg/m3 floats in a jar of water. Oil with a density of 750 kg/m3 is poured on the water until the top of the oil layer is 0.035 m below the top of the block. a) How deep is the oil layer? b) What is the gauge pressure at the block’s lower face?

A raft is constructed of wood having a density of 6.00x102 kg/m3. Its surface area is 5.50 m2 and its volume is 0.55 m3. When the raft is placed in fresh water, to what depth h is the raft submerged by its weight? The density of fresh water is 1000 kg/m3. Hint: Use Newton’s second to sum the forces (Buoyancy and weight) that are in equilibrium.
