Homework Statement Two sound fonts make plain armonic waves with the same amplitude and frequency. If f=200 Hz and V=340 m/s, the phase difference in a point situated 8m away from one font and 25 m away from the other one will be... Homework Equations V=Yf Y: Wave longitude Phase...

Forget it! I did it :smile: :rolleyes: :-p F/A*V=nRT F*L=nRT kX*L=nRT K=nRT/X.L K=nRT/2L*3L K=nRT/6L^2 Thanks anyways! :)

I forgot to tell that the longitude of the spring in equilibrium is 3L (which means that x=2L, I think?) So, what I did is: P= F/A F=-kX PV=nRT kX/A=nRT/V And volume is one, because its an ideal gas, so K=nRTA/X K=nRTA/2L And that's all I know

Problem with ideal gas law and a spring! Help please! Homework Statement We have a box divided in two parts by a piston without friction, and in one part there are n moles of an ideal gas and a Spring orf constant K and natural longitude L which keeps the piston in equilibrium. According to...
