While exploring a sunken ocean liner, the principal researcher found the absolute pressure on the robot observation submarine at the level of the ship to be about 413 atmospheres. The inside of the submarine is kept at atmospheric pressure. The density of seawater is 1025 kg/m3. Calculate the gauge pressure on the sunken ocean liner (in Pascals). Calculate the depth of the sunken ocean liner. Calculate the magnitude of the net force due to the fluid pressure only on a viewing port in the submarine at this depth if the viewing port has a surface area of 0.0100 m2. What prevents the ‘net force’ in part c from accelerating and moving the viewing port?
