Question

How high does a mercury barometer stand on a day when atmospheric pressure is 98.6 K pa?

Answer 1

Answer:

The mercury barometer would stand 0.725 m high.

Explanation:

ϱ = 13600kg/m³

g=10ms⁻²

Atmosphere pressure = 98.6 k pa

                                     = ϱgh

98600 pa = 13600 × 10 × h

h = 0.725 m

∴ 0.725 m high a mercury barometer would stand on a day when atmospheric pressure is 98.6 K pa.
