Please help solve the following problem:

Pro-Lab Question 3: When blood pressure is taken at the doctor's ofce, a standard measurement reads: 120 mmHg over TU mmHg, corresponding to the maximum and minimum pressures inside your vasculature as your heart courses through an entire cycle of a heartbeat. Would you classify these pressure readings as absolute pressure or gauge pressure (relative to ambient atmospheric pressure)? a. Convert 3ft] mmHg and 120 mmHg into SI pressure units, and into pounds per square inch {psi}. Now that your pressures are in SI units, critically think about your original claim regarding the heart's blood pressure as either gauge pressure or absolute pressure. How does this pressure compare to atmospheric pressure (convert 1 atm to mmHg, 81, and psi units}? Justify your reasoning regarding gauge pressure vs. absolute pressure in terms of how the body pressure compares to atmospheric pressure, which is a pressure that is being {nearly} uniformly applied to the body at all times. b. Imagine that a plunger is now activated that reduces the above airlled container from 0.5 liters to 0.45 liters, and that the temperature is kept at the room-temperature value 20\" C. What will be the increase in the pressure sP above the initial atmospheric value, in units mmIHg? How is this similar and different from the heart-blood system
