To create equal pressure above and below the wing
d)
To make the wing look really cool
22.

How does an airplane wing generate lift according to Bernoulli's principle?

a)

The weight of the airplane pushes down on the air, causing it to lift the wing

b)

The size of the wing determines the amount of lift it can generate

c)

The color of the wing creates a force that pushes the airplane upward

d)

The shape of the wing causes the air to move faster over the top surface, creating lower pressure and generating lift.
