Pressure at a Point in a Liquid at Equilibrium
Pressure at a point in a liquid means a force exerted perpendicularly by the liquid on unit area around that point in the liquid. In…
Explain Change in Atmospheric Pressure and Weather
With the change of time, the atmospheric pressure of a certain place also changes. The variation of water vapor in the air is the cause…
Explain Torricelli’s Experiment and Measure of Atmospheric Pressure
Take a glass tube about one meter long opened at one end having uniform diameter. Fill the whole tube with pure mercury. Close the open…
What is Atmospheric Pressure?
This earth is surrounded by air. Atmosphere has weight. So it has pressure. This very pressure on earth surface is almost 105 N per square…
Mathematical Example: Density
Question: What is the density of liquid of mass 2000 kg and volume 2 m3. Given Mass, m = 2000 kg volume, v = 2…
Define Density in terms of Physics
The space occupied by a body is called its volume. If we drop a piece of cork and a piece of iron of the same…
Mathematical Example: Pressure
Question: The mass of a woman wearing a shoe is 50kg. The area of the bottom of the shoe is 200 cm2. Find the pressure.…
