Ch 11 Quiz

The larger the area of an object

• more amount of pressure it exerts on

• equal amount of pressure it exerts on

• less amount of pressure it exerts on

• little or no pressure it exerts on

The buoyant force pushes objects

• in all directions

• downwards

• sideways

• upwards

Pascal's principle is

• The rule that when force is applied to a confined fluid, the change in pressure is transmitted equally to all parts of the fluid

• The rule that the buoyant force acting on a submerged object is equal to the weight of the volume of fluid displaced by the object

• The rule that the faster a fluid moves, the less pressure the fluid exerts

• A system that multiplies force by transmitting pressure from a small surface area through a confined fluid to a larger surface area

Archimedes' Principle states that the buoyant force on an object is equal to the

• weight of an object

• weight of the fluid the object displaces

• volume of the object

• volume of the fluid the object displaces

• fluid

• density

• buoyant force

• pressure

A material that can easily flow is a

• fluid

• lift

• pascal

• barometer

The inward pressure of the atmosphere on your hand is balanced by the

• muscle in your hand

• fluid pressure inside your hand

• upward pressure of the atmosphere on your hand

• muscles in your arm

Pascal is

• An upward force

• An instrument used to measure atmospheric pressure

• The rule that when force is applied to a confined fluid, the change in pressure is transmitted equally to all parts of the fluid

• A unit of pressure equal to 1 newton per square meter
