It is defined as the force per unit area

• Density

• Fluidity

• Pressure

• Buoyancy

It is the mass of a unit volume of a material or substance

• Density

• Fluidity

• Pressure

• Buoyancy

An object under water ________ its pressure as it goes deeper.

• doesn't change

• maintain

• decreases

• increases

If an object remains suspended at that depth, it means that?

• The buoyant force is greater than the object's weight

• The buoyant force is less than the object's weight

• The buoyant force is equal to the object's weight

• None of the above

He is the proponent of the principle of buoyancy

• Aristotle

• Archimedes

• Descartes

• Pythagoras

It is the upward force acting upon an object that is partially of wholly submerged in a fluid.

• Specific gravity

• Surface Tension

• Capillarity

• Buoyancy

When there is a greater upward force acting to an object that is submerged in water, the object has the tendency to?

• Float because the object is less dense than water

• Float because the gravity exerted on the object is greater than the upward force

• Float because the object is denser than water

• Float because the upward force is lesser
