What is the absolute pressure experienced at a point on the bottom of a swimming pool 9 meters in depth?

A hydraulic lift is used to lift a heavy machine that is pushing down on a 3.0 m2 piston (A1) with a force (F1) of 4,000 N. What force (F2) need to be exerted on a .050 m2 piston (A2) to lift the machine?

What is the absolute pressure in a depth of 100 meters of ocean water?

The interior of a submarine located at a depth of 45 meters is maintained at normal atmospheric conditions. Find the total force exerted on a .20 m by .20 m square window. ( Hint: find absolute pressure then force ☺)

what is the unit for pressure?

what is pressure?

Which one has the highest pressure?

what is pascal's principle?

You can exert 50 N of force on a piston with an area of 1.0 m2. If you are trying to lift a machine that weights 500 N, what must be the area of the piston on which the machine rests?

You decide to drive your vehicle, which has a weight of 100 N onto a piston that is 5.0m2, what weight machine can you lift if the piston on which it rests is 20 m2?
