When I ride the train, the song of the train whistle is an example of the Doppler Effect. Because a train is at the center of sound waves it produces, which radiate in concentric circles around it, there is no difference between the sound heard by someone on the platform, and the sound of the train as heard by someone standing behind the caboose.
The sun is bright and when its cold there is no sun
Moving a distal part of arms or legs to follow a circular path is called circumduction. This medical term is sometimes described as circular movement because the movements of hands and arms are tracing circles in the air or space. Circumduction is also described as conical movement.<span> </span>
Answer:
The magnetic compass shows no deflection.
Explanation:
- When a magnetic compass is placed on a current-carrying conductor, the compass needle shows deflection.
- When the direction of the current is reversed, the needle deflects in the opposite direction.
- This is due to the fact that the current-carrying conductor generates a magnetic field around it.
- If the direction of the current is reversed, the magnetic polarization changes.
- This phenomenon was first noticed by Oersted, and later it helped to develop electromagnetism.
