A satellite revolves round the earth. Air pressure inside the satellite is maintained at 76 cm of mercury. What will be the height of mercury column in a barometer tube 1m long placed inn the satellite?

Why is the height of mercury column nearly 76 cm in the tube ?

Two satellite A and B are revolving around the earth at the same height .The mass of the satellite A is twice that of B . What will be the speed of A that of B ?

Any satellite revolving round the earth in an orbit of height 36000 km with time period of 24 hours

Explain how is the height of mercury column in the tube of a simple barometer, a measure of the atmospheric pressure.

Barometer is constructed using liquid . What would be height of liquid column when mercury barometer reads 76cm

A barometer correctly reads the atmospheric pressure as 76cm of mercury. Water droplets are slowly introduced into the barometer tube by a dropper. The height of the mercury column first decreases and then become constant. If the saturation vapour pressure at the atmospheric temperature is 0.80cm of mercury, find the height if the mercury column when it reaches its minimum value.

Two satellite are revolving round the earth at different heights. The ratio of their orbital speeds is 2:1 . If one of them is at a height of the other satellite is (in km )
