Pressure depends on the folowing factors except?

• Density

• Nature of surface

• Height form a given point

• Gravitational acceleration

Which of the following factors does not affect size and amount of friction?

• Normal force

• Type of surface

• Direction of friction force

• Inclination of the surface

Define the term coefficient of friction

Which of the following statement is incorrect for friction occuring on an inclined plane?

• The normal force is given by mg sin (of the angle of repose)

• The angle of inclination is called the angle of repose

• When the angle of repose is increased and causes the object to move his angle becomes the limiting angle of repose

• The weight of the body is given by mg

Which of the following is not a state of equilibrium?

• Stable

• Neutral

• Balanced

• Unstable

A tank contains water to the depth of 600mm. Calculate pressure:

at a depth of 350mm

at the base of the tank

• 3.43kPa, 5.88kPa

• 5.88kPa, 3.43kPa

• 7.88kPa, 4.87kPa

• 343Pa, 5880Pa

Which of the following is not a factor governing pressure in fluids?

• Pressure at a given depth is equal in all direction

• Pressure is dependent on the shape of the container

• Pressure acts at right angles to the surface of the container holding the fluid

• Pressure is transmitted equally in all directions

------------- is given by mass divided by volume of the object.

The --------------- acting on a surface is defined by the perpendicular force acting on a surface per unit area
