An energy company operates a flat, horizontal solar collector array at a high-altitude research station on a mountain plateau. The total horizontal surface area of the collector array is 4200 m24200\text{ m}^24200 m2. The atmosphere exerts a downward force of 252,000,000 N252,000,000\text{ N}252,000,000 N on the top surface of this collector array.
Calculate the atmospheric pressure at the surface of the solar collector array. Use the equation:
pressure=forcearea \text{pressure} = \frac{\text{force}}{\text{area}} pressure=areaforceThe average atmospheric pressure at sea level is 101,300 Pa101,300\text{ Pa}101,300 Pa. Calculate the difference between the average atmospheric pressure at sea level and the atmospheric pressure at the surface of this solar collector array.
