The height of a mercury barometer is 75 cm at sea level and 50 cm at the top of a hill. Ration of density of mercury to that of air is `10^(4)`. The height of the hill is

the height of a mercury barometer is 76 cm at sea level and 50 cm at the top of a hill. Determine the height of the hill. (Densities of air and mercury are 1.36 kg m^(-3) and 13.6 xx 10^(3) kg m^(-3)) hint : Difference of pressure =76 cm - 50 cm = 26 cm of mercury 0.26 xx 9.8 xx 13.6 xx 10^(3) Nm^(-2) pressure due to h metre of air = h xx 9.8 xx 1.36 ]

The vertical height of mercury which a simple barometer can support at sea level is:

What will be the height of mercury column in a barometer it it is taken to the moon?

The angle of elevation of the top of a hill from the foot of a tower is 60^(@) and the angle of elevation of the top of the tower from the foot of the hill is 30^(@) . If the height of the tower is 50 m, what is the height of the hill?

The column of mercury in a barometer is 76 cm Hg. Calculate the atmosphere pressure I the density of mercury =13600kgm^(-3) (Take g=10ms^(-2) )

If the length of the mercury column in a mercury barometer is 76 cm, what is the equivalent height of the water column ?
