Answer:
See the explanation below
Step-by-step explanation:
First example
The water contained in a lake or tank is in equilibrium there is no movement of the fluid and the water exerts pressure on the bottom of the tank or lake.
Second example
A floating buoy that is on the high seas, the buoy is in static equilibrium and these developed forces allow the buoy not to sink.
Third example
A hydraulic press which uses the principle of pascal and the mechanical advantage due to the relation of areas, where applying a smaller force, you can obtain a much greater force, communicating the energy through a fluid such as oil.
Fourth Example
The atmospheric pressure, which depends on the height of a place above sea level, in this case the fluid is the air. Although the air cannot be seen, it exerts a pressure column on the bodies on the Earth's surface.
