Question

Which of the following is/are methods to find the direction of wind at a given place?

• A. While flying a kite, air exerts pressure on the kite due to which the kite flies. The direction in which the kite flies is the direction in which the wind is blowing
• B. While riding a bicycle, the direction in which it is difficult to ride the cycle is opposite to the direction of the blowing wind
• C. By freely suspending a N-S pole magnet
• D. All of these

Answer 1

Answer: (A), (B), (D)

The correct options are
A

While flying a kite, air exerts pressure on the kite due to which the kite flies. The direction in which the kite flies is the direction in which the wind is blowing

B

While riding a bicycle, the direction in which it is difficult to ride the cycle is opposite to the direction of the blowing wind

D

All of these

In the first (flying the kite) and the second (riding the bicycle) experiment, the force which is responsible for the action is the difference in air pressure. While considering the third example we can see that the force taken into consideration is magnetic in nature, hence this experiment cannot be used to determine the direction of wind.
