The third harmonic of an organ pipe that is open at both ends and is 2.25 m long excites the fourth resonant frequency above the fundamental in another organ pipe. Determine the length of the other pipe when A) it is open at both ends and B) when it is open at one end and closed at the other. The temperature is unknown, therefore the speed of sound is unknown.

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
