What is the SI unit use for hydraulic pressure?

• Kg/m³

• Pa

• kg m^-3

• N m²

The upward force exerted by a fluid is called the...

• buoyancy force

• density force

• fluidity force

• normal force

Fluid pressure is directed

• in all directions.
• only upward.
• only downward.
• always sideways.

How does an object's density affect the buoyant force acting on it?

• The more dense the object, the greater the buoyant force

• The less dense the object, the greater the buoyant force

• Density is equivalent to buoyant force

• Object density has no effect on buoyant force

What is the specific gravity?

• The amount of gravity on a specific material
• The ratio of the force of gravity
• Ratio of the density of a material and the density of water
• Ratio of density of water and oil

If two objects have the same volume but one has a greater mass, the one with greater mass 

• Has a lower density
•  Has a higher density
• Will float
• Will sink
