Question

How is the barometric height of a simple barometer affected if its tube is pushed down into the trough of mercury?

Answer 1

Explanation:

1. Since the increasing air pressure exerts more strain on the reservoir, the mercury throughout the column increases. By limiting reservoir power, low pressure permits mercury to fall to a lower column level.
2. When the tube of a basic barometer is pushed down into the troughs of mercury, the atmospheric force upon that container has been modified by the mercury there until the heaviness of the mercury column is sufficiently balanced.
3. As a result, the barometric height of a basic barometer is unaltered.
