Compute all parts of given question:
Question: A storage tank of negligible mass and 30m high is filled with gasoline.
Part A: Calculate the gauge pressure and absolute pressure at the bottom of the tank.
Part B: Calculate the force that acts on a square access hatch at the bottom of the tank that measure 0.5m x 0.5m.
Part C: Given that the tank is shaped like a right circular cylinder with a height of 30 m and with a base radius of 10m. The tank is attached to a steel cable of negligible mass and immersed in water. Calculate the tension (force) in the cable before and after it is immersed in water.
Please use as much detail as possible in your answer for above question. Thanks.
