How does pressure change when the force is applied on a smaller area?

• Pressure increases

• Pressure decreases

• Pressure remains the same

• Pressure cannot be determined

How does pressure change when the force is applied on a larger area?

• Pressure increases

• Pressure decreases

• Pressure remains the same

• Pressure cannot be determined

What is the pressure exerted by a liquid column at a depth 'h'?

• Ahph

• hpg

• A/h

• pgh

What is the total pressure inside a liquid column at a depth?

• PO + hpg

• PO - hpg

• PO * hpg

• PO / hpg

What is Pascal's law?

• The pressure exerted anywhere in a confined liquid is transmitted equally and undiminished in all directions throughout the liquid

• The pressure exerted anywhere in a confined liquid is transmitted only in one direction throughout the liquid

• The pressure exerted anywhere in a confined liquid is transmitted unequally and diminished in all directions throughout the liquid

• The pressure exerted anywhere in a confined liquid is transmitted unequally and undiminished in all directions throughout the liquid

What is the purpose of a hydraulic press?

• To measure atmospheric pressure

• To measure liquid pressure

• To transmit pressure

• To increase pressure
