Static Fluids and Buoyancy Quiz

Which principle states that a change in pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid and to the walls of its container?

• Archimedes' Principle

• Pascal's Principle

• Bernoulli's Principle

• Newton's First Law

What is the SI unit of pressure?

• Newton

• Pascal

• Joule

• Watt

Which device is used to measure atmospheric pressure?

• Manometer

• Barometer

• Thermometer

• Hydrometer

What constant is typically used for the acceleration due to gravity in fluid statics problems?

Archimedes' Principle is most closely associated with which physical concept?

• Surface tension

• Buoyancy

• Viscosity

• Capillarity

A manometer is primarily used to measure:

• Temperature

• The density of a solid

• The pressure of a gas in a container

• The speed of a fluid

Which of the following best describes buoyant force?

• The force that opposes gravity in a fluid

• The force that causes objects to sink

• The force that increases with temperature

• The force that acts parallel to the surface

According to Archimedes' Principle, the buoyant force on an object submerged in a fluid is equal to:

• The weight of the object

• The weight of the fluid displaced by the object

• The mass of the object

• The volume of the object

Which of the following is a correct statement about Pascal's Principle?

• Pressure increases with depth in a fluid

• Pressure applied to a confined fluid is transmitted equally in all directions

• The buoyant force equals the weight of the object

• The pressure at the surface is always zero
