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?

A barometer is constructed with its tube having radius 1.0 mm. Assume that the surface of mercury in the tube is spherical in shape. If the atmospheric pressure is equal to 76 cm of mercury, what will be the height raised in the barometer tube? The contact angle of mercury with glass 135^@ and surface tension of mercury =0.465Nm^-1 . Density of mercury =13600kgm^-3 .

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

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

A berometer correctlu 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 tgemperature 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 )

A satellite of mass , os revolving round the eartj at height of 10R , where R is the radius of earth. What is the kinetic energy of satellite.

Height of mercury in a barometer is h_0 = 76. 0 cm at a temperature of theta_1 = 20^(@)C . If the actual atmospheric pressure does not change, but the temperature of the air, and hence the temperature of the mercury and the tube rises to theta_(2)= 35^(@)C , what will be the height of mercury column in the barometer now? Coefficient of volume expansion of mercury and coefficient of linear expansion of glass are gamma_(Hg) =1.8xx10^(-4).^(@)C^(-1), alpha_(g)=0.09xx10^(-4).^(@)C^(-1)

Satellite is revolving around earth. If its height is increased to four times the height of geostationary satellite, what will become its time period ?
