Han stands at the rim of the Grand Canyon and yodels down to the bottom. He hears the yodel echo back from the canyon 5.20 seconds later. If sound travels at 340 m/s in air, how deep is the canyon at this location? [Hint: The answer is not equal to 1768 meters]

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 3.00 ms . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
