Answer 2

Answer:

please mark me as the BRAINLIEST

Explanation:

a) Mercury in the tube adjusts until the weight of the mercury column balances the atmospheric force exerted on the reservoir. High atmospheric pressure places more force on the reservoir, forcing mercury higher in the column. Low pressure allows the mercury to drop to a lower level in the column by lowering the force placed on the reservoir.

When the tube is pushed down into the trough of mercury the height of mercury column above the surface of the bottom surface remains the same.
