Answer :
Final answer:
The pressure difference on an airplane wing is determined by the difference in air speed over the wing.
Explanation:
The pressure difference on an airplane wing can be calculated using Bernoulli's principle. Bernoulli's principle states that as the speed of a fluid increases, its pressure decreases. Since the air flows faster over the top of the wing, the pressure on the top surface of the wing will be lower compared to the bottom surface. The pressure difference is determined by the difference in air speed over the wing.
However, the options given for the pressure difference in the question (a) P=115Pa, (b) P=115N/m2, (c) P=115Nm−2, (d) P=115N) are incorrect. The unit for pressure is Pascal (Pa), which is the same as N/m². Therefore, the correct answer is (b) P=115N/m².
