A flat-roofed scientific habitat is constructed on the Altiplano high plateau. The flat roof of the habitat has a surface area of 180 m2180\text{ m}^2180 m2. The atmosphere exerts a downward force of 1.08×107 N1.08 \times 10^7\text{ N}1.08×107 N on the roof.
Calculate the atmospheric pressure at the altitude of the habitat. Use the equation:
pressure=forcearea \text{pressure} = \frac{\text{force}}{\text{area}} pressure=areaforceThe average atmospheric pressure at sea level is 101,350 Pa101,350\text{ Pa}101,350 Pa. Calculate the difference between the average atmospheric pressure at sea level and the atmospheric pressure at this high-altitude habitat.
