Why does a whip make a sharp crack sound when it is snapped?
have u ever hard of the thunders, u can hear the same noise. that's because there is a rapid expansion of air with extreme speed, if you have noticed, you will see the light bolt than a couple of seconds later you will hear the noise. With the whip it crashes the air and expands it making the noise * * * * * Only partially correct. The answer has nothing to do with the time lag between seeing a lightning bolt and hearing the thunder. That is simply a result of the fact that light travels much faster than sound. When a whip is cracked, it end flicks at a speed that is greater than the speed of sound. The resultant pressure wave travels at a speed greater than the speed of sound creating a sonic boom - in the same way that jets cause a sonic boom.

Does smell travel quicker than noise?
Probably not. "Noise" consists of sound waves, which travel, appropriately enough, at the speed of sound ... something like 340 meters per second. "Smell" consists of molecules or particles that physically travel from the source to your nose. Almost by definition, the speed of the physical particles has to be less than the speed of sound waves in air.
