#1
Which of the following is an example of a fluid?
#2
What causes buoyancy in fluids?
Gravity
Friction
Magnetism
Temperature
#3
What happens to the pressure exerted by a fluid if the area over which it is exerted decreases?
Pressure increases
Pressure decreases
Pressure remains constant
Depends on the type of fluid
#4
What is the SI unit of force?
Newton (N)
Pascal (Pa)
Joule (J)
Watt (W)
#5
What is the SI unit of pressure?
#6
Which of the following represents Pascal's principle?
Pressure increases with depth in a fluid
Pressure is inversely proportional to the volume of a confined gas
Pressure applied to a fluid is transmitted undiminished to every part of the fluid and to the walls of its container
The buoyant force acting on an object in a fluid is equal to the weight of the fluid displaced by the object
#7
What is the effect of increasing the density of a fluid on pressure?
Increases pressure
Decreases pressure
No effect on pressure
Depends on the temperature
#8
Which factor affects fluid viscosity?
Temperature
Density
Pressure
Volume
#9
What is the equation for calculating the force exerted by a fluid on a surface?
Force = Pressure × Volume
Force = Pressure / Area
Force = Mass × Acceleration
Force = Density × Volume
#10
What is the formula to calculate pressure?
Pressure = Force / Volume
Pressure = Density × Acceleration due to gravity
Pressure = Mass / Volume
Pressure = Force / Area
#11
Which statement describes an example of Bernoulli's principle?
An increase in velocity of a fluid leads to a decrease in pressure
Pressure applied to a confined fluid is transmitted equally in all directions
The buoyant force on an object is equal to the weight of the fluid displaced
The pressure in a fluid increases with depth
#12
What is the equation for hydrostatic pressure?
P = F/A
P = ρgh
P = mgh
P = Fd
