What happens if a sound wave is compressed?
it is unclear what you mean. One form of 'compression' would be the dopplar effect whereby a object producing sound is moving towards the listener. The sound heard by the listener is of a higher frequency than the sound that is produced.
When you observe objects in space why does it seem that the objects you observe are moving across the sky?
Because the earth is rotating.

How does guitars produce sound?
There are two methods - acoustic and electric. Acoustic:- When the strings are played, the sound of the vibration is amplified by the air moving inside the guitar. The sound 'escapes' through the sound hole, and travels to the ears of the listener. Electric:- The movement of the strings induces an electric current in the guitar's pick-up coil. This is converted into electrical energy, which is fed to an amplifier. The amplifier sends the electrical signal to the speaker - which the listener hears.
Why does wind chill occur?
In physics, we observe what happens and try to predict it, seldom does that answer why something happens. wind chill is caused by "convection cooling". Air (wind) moving past a body (convection) takes more heat away than when air is not moving (radiation). A perfect example is blowing air over a spoon of soup to cool it.
If you were travelling at the speed of sound would you be able to listen to the radio?
The question is incomplete. If the radio is moving along with the listener then listening is possible. If the radio is at rest then the listener cannot hear the sound vibrations given out by that radio.
