The height of mercury barometer is h when the atmospheic pressure is `10^(5)Pa`. The pressure at x in the shown diagram is

How high does the mercury barometer stand on a day when atmospheric pressure is 98.6 kPa ?

What will be the length of mercury column in a barometer tube when the atmospheric pressure is x cm of mercury and the tube is inclined at an angle phi with the vertical direction ?

A mercury barometer always reads less than actual pressure.

What will be the length of mercury column in a barometer tube when the atmosperic pressure is 75 cm of mercury and the tube is inclined at an angle of 60^@ with the horizontal direction?

Why mercury is used in barometer for measuring atmospheric pressure?

Why mercury is used in barometer for measuring atmospheric pressure?

What will be the length of mercury column in a barometer tube, when the atmospheric pressure is 76 cm of mercury and the tube is inclined at an angle of 30 ^(@) with the horizontal direction ?

A barometer tube of length 90 cm contains some air above mercury. The reading of the mercury level is 74.8 cm when the atmospheric pressure is 76 cm and temperature is 30^@C . If the reading is observed to be 75.4 cm on some another day when temperature is 10^@C , then what will be true pressure?

Why is the reading of a mercury barometer always less than actual pressure?

Explain why does the mercury level in a barometer go down when atmospheric pressure decreases?
