If a force of 20 N is applied and the distance between the hinge of the door and the point of application of force is 40 cm, then find the magnitude of moment of force.
8 Nm
The unit of pressure is __________
Pascal
Why can camels cross the desert and not horse or a donkey?
Because it has broad feet hence exerts less pressure
Calculate the force if the area of cross-section is 20 cm^2 and the pressure exerted by the body is 12500 Pa.
25 N
The S.I. unit of force is kgf. (True/False)
False
The pressure and thrust are related as
Pressure = Thrust/Area
Nose bleeding may occur at a high altitude because
The atmospheric pressure decreases
A force of 16 N acts on an area of 50 cm^2. What is the magnitude of pressure in pascal?
3200 Pa
Which instrument is used to measure atmospheric pressure?
Barometer
Mercury is used as barometric liquid as it does not vaporise under vacuum conditions. (True/Flase)
True
As we move on a higher altitude the pressure increases/decreases.
Decreases
Define lateral pressure.
The pressure exerted by the fluids (liquids/gases) on the sides of containing vessel is called lateral pressure.
