Multiple Choice

Archimedes' Principle states that...

• The buoyant force acting on an object equals the volume of the fluid displaced by the object. 

• The buoyant force acting on an object equals the weight (force of gravity) of the fluid displaced by the object.

• The buoyant force acting on an object will always be equal.

Multiple Choice

What is the equation used to calculate pressure?

• pressure= force/mass

• pressure=area/force

• pressure =mass/volume

• pressure=force/area

Multiple Choice

What is the unit of measurement for pressure?

• pascal

• milliters

• grams

• meters

Multiple Choice

 

If a piston has a face of 2cm² and a force of 5N is applied what is the total pressure?

• 10N/m²

• 2.5N/cm²

• 0.4N/cm²

• 10N/cm²

Multiple Choice

Pascal states that

• Pressure is force per unit area

• When force is applied, the pressure is transmitted equally through the fluid

• When velocity is higher, the pressure is lower

• Pressure transmitted is directly proportional to the force applied

Poll
