The value of g at a place decreases by 2%. The barometric height of mercury

If value of acceleration due to gravity at a place decreases by 3% the Ti find the change in height of mercury in a barometer at that place.

If value of acceleration due to gravity at a place decreases by 3% the Ti find the change in height of mercury in a barometer at that place.

The moisture present in mercury increases the barometric height of simple barometer.

The unit torr is related to the barometric height as :

Explain the factors that affect barometric height.

What is indicated by sudden fall in barometric height?
