Pressure in Fluids and Atmospheric Pressure

How is this barometer different from the other two?

What is the S.I. unit of thrust?

Which instrument is used to measure atmospheric pressure?

Identify the instrument.

Why does a fountain pen leak at a high altitude?

Convert 1 mm of Hg into Pascal. Take density of Hg = 13.6 X 10^3 kg m^-3 and g = 9.8 m/s^2

Thrust is a scalar quantity, (True/False)

The normal atmospheric pressure is __________

Identify the picture

The S.I. unit of pressure is _______________

At sea level, the atmospheric pressure is 1.04 X 10^5 Pa. Assuming g = 10 m/s^2 and density of air to be uniform and equal to 1.3 kg m^-3. Find the height of the atmosphere.
