Pressure In A Fluid (GCSE Physics)

A fluid exerts pressure because its particles collide with surfaces; which direction is this pressure exerted?

A hydraulic jack multiplies force by using a small input piston and a larger output piston. The reason is:

Which equation gives hydrostatic pressure at depth h:

A manometer shows a higher column of liquid on the side open to air than the side connected to a closed container. This indicates:

A diver at 10 m depth feels ear pain. This is due to:

In a U-tube, different liquids settle to different heights because of:

A cubic block 0.20 m side floats with half its volume submerged. The block’s density is:

A diver goes from 2 m to 6 m depth in seawater (? = 1025 kg/m3, g = 9.8 N/kg). The increase in pressure (approx) is:

A garage measures tyre pressure with a gauge showing 220 kPa. This is the gauge (above atmospheric) reading. The absolute pressure in the tyre (atmospheric ~101 kPa) is:

A syringe contains trapped air. When you push the plunger slowly reducing volume, the pressure increases because:

For a given depth in the same liquid, hydrostatic pressure is doubled if:
