Read the statement.
The air that flows over the top part of an airplane's wing moves faster than the air that flows across the bottom. This faster moving air causes the wing to rise.
Which of the following principles or laws helps explain why the wing rises?
Bernoulli
pascal
boyle
charles
Bernoulli's principle
The difference in the velocities of the air creates a difference in pressure on both sides of the wing, which is described by Bernoulli's principle.
thank you
To determine which principle or law helps explain why the wing rises when the air flows over it, we can examine the information provided in the statement. This particular phenomenon is commonly explained using the Bernoulli principle.
The Bernoulli principle states that as the speed of a fluid (in this case, air) increases, its pressure decreases. In the context of an airplane's wing, as the air flows over the top part of the wing and accelerates, its speed increases, resulting in lower air pressure above the wing. At the same time, the air flowing across the bottom part of the wing moves at a slower speed, resulting in higher air pressure. This difference in air pressure creates an upward force called lift, which causes the wing to rise.
Therefore, the correct answer is Bernoulli.
