Question

Describe wingtip vorticies?

a) They are created by the pressure difference between the upper and lower surfaces of the wing.
b) They are circular patterns of rotating air that form at the tips of aircraft wings.
c) They are caused by the interaction between the engine thrust and the surrounding air.
d) They occur due to turbulence in the atmosphere during flight.

Answer 1

Wingtip vortices are circular patterns of rotating air that form at the tips of aircraft wings due to pressure difference between the upper and lower surfaces of the wing.

Step-by-step explanation:

Wingtip vortices are circular patterns of rotating air that form at the tips of aircraft wings. These vortices are created due to the pressure difference between the upper and lower surfaces of the wing. The faster-moving air over the longer upper surface creates lower pressure, while the slower-moving air under the wing creates higher pressure. This pressure difference creates a swirling motion of air at the wingtip, which can be observed as a visible vortex.
