Will rate high if correct answer thank you!!

2. Using the given, solve: A. A cylindrical disk of wood weighing 50.0 [N] and having a diameter of 25.0 [cm] oats on a liquid of density p = 0.750 [g/cm3]. 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 oat at the _ interface between a layer of oil of unknown density p011, and water (pwml. = H 1000 [kg/map inside a container as shown. The density of the wood is pwood = 800 [kg/m3]. What must be the density ofthe oil so that only 30. 0% of the wood is submerged in water? C. Water is owing through a pipeline shown on the . right. The radii ofthe pipe at points 1 and 2 are 0. 500 [m] and 1.50[m], respectively. The volume ow rate through the pipeline is 2.50 [US]. 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? 5.00 [m]
