The figure shows a pond with two fish P and Q.
What is the correct relation of the water pressures on fish P and fish Q?
Water pressure on fish Q > Water pressure on fish P.
Water pressure on fish Q < Water pressure on fish P.
Water pressure on fish Q = Water pressure on fish P.
Hydraulic systems use natural gas as an enclosed fluid.
True
False
To find the pressure on an object you need to calculate:
pressure = F/A
pressure = A/F
pressure = F x A
pressure = A x F
