Ok /sci/ I am trying to figure this phys question out, and I just dont understand it. The question is as follows:

The speed of waves on a guitar string is
126 m/s.
What is the fundamental frequency of the
string when the effective string length is 72.9
cm?
Answer in units of Hz

Now I dont want an answer Id like to know how to figure it out.

I know its dealing with harmonics, cause the second question is asking:
What is the second harmonic?
Answer in units of H

If you guys could help itd be appreciated very much.

10kPa inside the gas sphere still means a 90kPa difference between the inside and outside.
Take a plastic 2l bottle, pour in a little boiling water and screw the cap on... when the water and air in the bottle cool, the bottle gets crushed... try and stop this with out making the bottle any heavier.
