Question

the pressure exerted on a scuba diver at sea level is 14.70 pounds per square inch (psi). for each foot the scuba diver descends below sea level, the pressure exerted on the scuba diver increases by 0.44 psi. what is the total pressure, in psi, exerted on the scuba diver at 109 feet below sea level?
a 62.66
b 33.26
c 14.70
d 0.44

Explanation:

Step1: Calculate pressure increase

Pressure increase = 0.44 psi/foot 109 feet = 0.44 109 = 47.96 psi

Step2: Calculate total pressure

Total pressure = Sea level pressure + Pressure increase = 14.70 psi + 47.96 psi = 62.66 psi

Answer:

A. 62.66
