Question

B) Aerodynamic drag force is lower in cold climate.
true or false

Answer 1

Answer:

True

The aerodynamics force is directly proportional to the temperature.

Thus lower force has lower temperature.

Answer 2

Answer:

In a cold climate, the drag force is reduced. The statement is true.

Explanation:

• Drag is the aerodynamic pressure that opposes a plane's motion through the air. Drag is generated through each part of the airplane.
• Drag is a mechanical pressure. It's far generated with the aid of interaction and getting in touch with a solid body with fluid.

The viscosity of air decreases as we lower the temperature. This is due to the fact speed of air molecules decreases making the air molecules collide less regularly with the item. So drag pressure decreases because viscosity decreases.

So, the statement is true.
