Which of the following statements is true regarding air flowing through a venturi?

As the velocity of the air increases, the pressure decreases.

an object's resistance to a change in velocity.

The angle of attack at which an airplane wing stalls will

remain the same regardless of gross weight.

The term "angle of attack" is defined as the angle between the

chord line of the wing and the relative wind.

In the absence of any external forces, an object in motion

will continue moving at the same velocity.

A stall occurs when the smooth airflow over the unmanned airplane's wing is disrupted, and the lift degenerates rapidly. This is caused when the wing

exceeds its critical angle of attack.

Which of the following statements is true regarding air flowing through a venturi?	As the velocity of the air increases, the pressure decreases.
Inertia is	an object's resistance to a change in velocity.
The acute angle A is the angle of fig 1	attack.
The angle of attack at which an airplane wing stalls will	remain the same regardless of gross weight.
The term "angle of attack" is defined as the angle between the	chord line of the wing and the relative wind.
In the absence of any external forces, an object in motion	will continue moving at the same velocity.
A stall occurs when the smooth airflow over the unmanned airplane's wing is disrupted, and the lift degenerates rapidly. This is caused when the wing	exceeds its critical angle of attack.
