Pressure - Physics Form 5

What is the equation used to calculate pressure?

• force/mass

• area/force

• mass/volume

• force/area

Which diagram represents the correct force of the fluid acting on a cube?

• 
• 
• 
• 

Pressure in liquids are affected by the following except

• depth, h

• density, ρ

• mass, m

• gravity, g

What is the formula for density?

• mass × volume

• mass / volume

• mass + volume

• mass - volume

S.I. unit for pressure is

• Pa

• N m^-1

• Psi

• mm Hg

What will happen to the pressure in a liquid when its density increase?

• lower

• greater

• not affected

The manipulated variable in the experiment as in the picture is

• depth

• density

• gravity

• mass

The diagram show two different liquids; water and liquid P in a U-tube. Which liquid is less dense?

• water

• liquid P

• both liquids has same density

The density of water is 1000 kg m^-1. Calculate the density of liquid P, in kg m^-1.
