Hey, these two questions are off a take home test I was given. I could use a good grade on them so could anyone give me a hand? thanks A raft with a length of 8.0m, a width of 1.6m, a thickness of 0.11m, and a density of 690.0kg/m^3 is placed in a river. How far below the water's surface does the bottom of the raft sink? (recall that fresh water has a density of 1.00x10^3 kg/m^3) The absolute pressure below the surface of a freshwater lake is 2.43 x 10^5 Pa. At what depth does this pressure occur? Assume that atmospheric pressure is 1.01 x 10^5 Pa and that the density of the water is 1.00 x 10^3 kg/m^3.
