When a person swims under water, water pressure is felt acting on the person's eardrums. The pressure is due to
Less water above the person
Large surface area of the swimmer
Weight of the water above the person
Volume of water
When you increase your depth under water, the water pressure on your body
increases
decreases
stays the same
How do you Calculate Pressure
Force(N)/Area(m2)
Force(kg)/Area(mi2)
Area(m2)/Force(N)
Diagram shows the design of a dam. Why does the thickness of the dam increase with its depth?
