2. A. Solve the following: A cylindrical disk of wood weighing 50.0 [N] and having a diameter of 25.0 [cm] floats on a liquid of density p = 0.750 [g/cm]. The cylinder of liquid is 60.0 [cm] high and has a diameter that is the same as that of the wood. What is the gauge pressure halfway down the liquid? B. For your science exhibit, you want to make a block of wood (Pwood the interface between a layer of oil of unknown density Poil, and water (Pwater 1000 [kg/m]) inside a container as shown. What must be the density of the oil so that only 30.0% of the wood is submerged in water? C. Water is flowing through a pipeline shown on the right. The radii of the pipe at points 1 and 2 are 0.500 [m] and 1.50 [m], respectively. The volume flow rate through the pipeline is 2.50 [L/s]. If the pressure at point 1 in the pipe is 200 [kPa], what is the pressure at point 2, located 5.00 [m] above point 1? 1 = 800 [kg/m])) float at 2 Oil wood water 5.00 [m]
