The diagrams show, to the same scale, the vertical sections of a set of circular vessels, each containing the same depth of water.
The water exerts the same pressure on the base of each vessel.
The water exerts the greatest pressure on the base of vessel S.
The water exerts the greatest pressure on the base of vessel P.
The water exerts the same force on the base of each vessel.
Pressure rxerted by air on the earth's surface
Pressure
Atmospheric pressure
Heat pressure
The pressure inside the syringe will decrease if we move the plunger in:
Direction A
Direction B
We don't have to move the plunger as the pressure will change on its own.
None of the above answers.
The reason gases can be compressed is because:
The particles are very close together.
The particles are merely vibrating.
The particles are unable to move.
The particles are very far apart.
How do you Calculate Pressure?
Force(N) / Area(m2)
Force(kg) / Area(mi2)
Force(kg) / Area(mi2)
Area(mm2) / Force (kg)
If an object's surface area is smaller does it create more or less pressure?
More
Less
The same
None
What is the correct formula to calculate pressure?
P= F x A
P= F / A
P= A / F
P= A + F
Which situation produces more pressure on the floor?
standing on one foot
standing on two feet
standing on four feet

What is the SI unit of pressure?
Kg/m3
Pa
kg m-3
N m2
