Bernoulli's principle can be used to explain the lift force on an airplane wing. How must an airplane's wing be designed to ensure that Bernoulli's principle is applicable? A. Airplane wings must be designed to ensure that air molecules move more rapidly past the bottom surface of the wing, creating a region of higher pressure. B Airplane wings must be designed to ensure that air molecules are deflected upward after hitting the wing. C Airplane wings must be designed so that they are thick enough to ensure a significant pressure difference between the top and bottom surfaces of the wings. D Airplane wings must be designed to ensure that air molecules move more rapidly over the top surface of the wing, creating a region of lower pressure. E Airplane wings must be designed to ensure that air molecules are deflected downward after hitting the wing.

Answer:

D. Airplane wings must be designed to ensure that air molecules move more rapidly over the top surface of the wing, creating a region of lower pressure.

Explanation:

Bernoulli's theory operates on the assumption that its shape makes the air travel more over the top of the wing than under it as a plane moves through the air. Due to the pressure difference, wings feel a lifting force and create lift force. when pressure decrease than the velocity of the fluid will increase.

Therefore the answer is D.

Airplane wings must be designed to ensure that air molecules move more rapidly over the top surface of the wing, creating a region of lower pressure.

Option D is correct

What is Bernoulli's principle?

Bernoulli's principle simply states that an increase in the speed of a fluid occurs at the same time with a reduction in static pressure.

Generally, Because of the pressure difference, wings feel a lifting force and create a lift force when pressure decreases lower than the velocity of the fluids increase.
