Plasma
What is the unit of pressure?
Newton
Watt
Pascal
Joule
What is the definition of density?
Energy per unit volume
Force per unit area
Mass per unit volume
Volume per unit mass
Which type of stress do fluids not sustain?
Bending stresses
Compressive stresses
Tensile stresses
Shearing stresses
What is the direction of the force producing pressure in fluids?
Parallel to the area
Perpendicular to the area
Tangential to the area
Opposite to the area
What is the formula for pressure in fluids?
P = F + A
P = F x A
P = F/A
P = F - A
What is the density of a substance defined as?
Force per unit volume
Mass per unit area
Volume per unit mass
Mass per unit volume
What is the variation of pressure with depth in fluids?
Inverse
Constant
Exponential
Linear
What is the pressure at a depth h below a point in a liquid?
P = P0 + ρgh
P = P0 - ρgh
P = P0 / ρgh
P = P0 x ρgh

Plasma
Gas
Liquid
Solid
What is the definition of pressure?
Mass per unit volume
Volume per unit mass
Force per unit area
Force per unit volume
Which type of fluids are described by fluid dynamics?
Fluids in a vacuum
Fluids at rest
Fluids in motion
Fluids under pressure
What is the unit of pressure in SI?
Newton
