Question 3 1 pts -kh = If the temperature is constant, then the atmospheric pressure p (in pounds/square inch) varies with the altitude above sea level in accordance with the law P = Poe where Po is the atmospheric pressure at sea level and kc is a constant. If the atmospheric pressure is 16 lb/in 2 at sea level and 11.5 lb/in 2 at 4000 A, find the atmospheric pressure at an altitude of 12000 A. O 6.91b/in? 2 0 4.91b/in? 2 5.91b/in2 O 3.91b/in2 2 O 7.91b/in?
