A well acts as a closed pipe. When
wind blows across the top, it
creates a fundamental frequency of
30.6 Hz. How deep is the well?
(Speed of sound = 343 m/s)
(Unit = m)

The slope of a velocity time graph over any interval of time gives the during that interval

Name the non metal condut electricity

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?
