#### Answer:

(a).

(b).

#### Explanation:

Absolute pressure = gauge pressure + atmospheric pressure.

"Gauge Pressure" is the pressure due the liquid alone. This is given by:

=

To get the absolute pressure we need to add on the pressure due to the weight of the air above it. We add on the atmospheric pressure which I will assume to be

Absolute pressure
