You sit at the outer rim of a Ferris wheel that rotates at 63 revolutions per minute. What would your rotational speed be if you were instead clinging to a position halfway
from the center to the outer rim?

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?
