I'm working on a program to figure stresses on a helical type spring and the term 'Wahl Factor' keeps coming up. What is it? What does it measure?
Thanks for any help you can give me!

How would you calculate the wavelength of a photon density wave if:

f (frequency)=200 MHz
ua (absorption coefficient)=0.1 cm^(-1)
us' (reduced scattering coefficient)=10 cm^(-1)
n (index of refraction)=1.37

I've look everywhere. I just need something to get me started.

Thanks!

Eight lights are connected in parallel to a 110-V source by two long leads of total resistance 1.6 ohms. If 240 mA flows through each bulb, what is the resistance of each, and what fraction of the total power is wasted in the leads?


Please show work so I will understand how to work similar problems.

I have a beep sound file, I record it using a jack from the output of the soundcard to the input of the mic, the file is displayed with a lot of noise and the beeps having a known frequency (1-9) cannot be seen clearly, what filters or technique can I use to extract the beeps.
thank you .

I have a large pre-amp circuit with 4 stages of amplification. The power supply has +24V, +12V, -12V and +5V outputs. The noise from the -12V supply is getting into the final outputs. Why? Is there a problem with one components that uses the -12V in the final output? Is there a problem with one of the AC bypass caps on the -12V line? The power supply isn't the problem. It works fine with the other preamp boards. If you need more info, let me know? Thanks.
