A pressure-measuring device indicates that the blood pressure of a normal person oscillates between 120mm Hg (at the peak of the heartbeat) and 80mm Hg (between heartbeats). When the pressure-measuring device is taken off of the person and used to measure the pressure of the room air, it indicates a value of 0. For a normal person at sea level (where the air pressure = 1atm)

(a) What are the gauge pressure at the peak and between beats?

(b) What are the absolute pressures at the peak and between beats?
