as a submarine descends into the deep ocean, the pressure it must withstand increases. At an altitude of - 700 metres, the pressure is 50 atm, and an altitude of -900 meters, the pressure is 70 atm. For every 10 meters the submarine descends, the pressure it faces increases by n, where n is a constant. What is the value of n
