D Question 4 10 pts A tank is 8 m long, 4 m wide, 2 m high, and contains kerosene with density 820 kg/m to a depth of 1.5 m. Use g = 9.8 m/s for acceleration due to gravity. Round your answers to the nearest whole number. A. Find the hydrostatic pressure on the bottom of the tank. Pa B. Find the hydrostatic force on the bottom of the tank. C. Find the hydrostatic force on one of the smaller ends of the tank. N Previous NextD Question 5 10 pts A plate is shaped like a right triangle. Its horizontal leg is 10 feet long and its vertical leg is 5 feet long. The plate is submerged vertically in water so that its tip is 2 feet below the water's surface. Express the hydrostatic force against one side of the plate as an integral. Hint: Since measurements are in feet, use the weight density of water, o = 62.5 lb/ft3. 2 ft 5 ft 10 ft ( 125(27 - 21) da [ 125(x2 - 2x) da ( 125 (27 + 2x) du ( 9800(27 - 2x) dz ( 9800 (2 + 2x) daQuestion 6 10 pts Three paintemasses mg are located on the meaxis: The mass M] : 12 Is located a! the point a; : 73. the mass m; : 15 is loca\\ed at the point a; : 2, and mass m3 : 20 is located at the point a: : 8. ml=12 m2=15 m3=20 ..OOiI.O1iOIOI> 3 0 2 8 I Find the moment M of the system about the origin and the center of mass 5.
