1. An altimeter is a device that measures the height of a plane above the ground. It works based on air pressure according to the formula h = 18400log Po Р where h is the height above the ground in meters, P is the air pressure at that height, and Po is the air pressure on the ground at takeoff. Air pressure is measured in kilopascals (kPa). a. Air pressure on the ground was 102 kPa. If the airplane instruments measure a pressure of 32.5 kPa outside the plane, what is the height of the airplane to the nearest meter? b. What is the outside air pressure for a plane flying at 11 000 meters? Assume a ground pressure 102.5 kPa. Round to one decimal place. c. How high would a plane have to be flying when it encountered air pressure in the air that was half the air pressure on the ground? Round to the nearest meter.
