Question

Quizplus · Accepted Answer

To keep the airplane up, the pressure difference between the top and bottom of the wings must be equal to the weight of the airplane divided by the total area of the wings. Therefore, the pressure difference is (30,000 kg x 9.8 m/s^2) / 100 m^2 = 2,940 Pa. So, the correct choice is B.
