plz answer fast

Solution :


If a sound wave travels from east to west, the particles of a air move in East-West direction (option a).
Sound is a longitudinal wave, the particles of a medium move in a direction parallel to the direction of wave propogation.

In solid medium sound travels fastest (option a).
This is because the molecules of solids are closest together and can transmit the vibrations faster than any other medium. 

Kindly post the different questions in different thread.
