A railroad worker drives a spike into a piece of rail with a hammer. A worker about 100 m down the track has his ear on the same piece of rail. Will he hear the sound of the strike through the rail or air first?
Explanation:
The speed of sound is more in solids as compared to liquids and air. this is because sound is a vibrational kinetic energy that is passed from molecule to molecule of a medium.
Since the molecules in the rail are closer to each other,the worker will hear the sound of the strike through the piece of rail before air.
