What is the atmospheric pressure at sea level?

750 mmHg

760 mmHg (correct)

770 mmHg

780 mmHg

What is the relationship between the length of Column A and the force?

The length of the column is inversely proportional to the force

The longer the column, the smaller the force

The longer the column, the bigger the force (correct)

The length of the column has no effect on the force

What is the indication of the longer Column A?

The pressure is bigger (correct)

The pressure is smaller

There is no force or pressure

The force is smaller
