Apen rolls off a 0.55–meter high table with an initial horizontal velocity of 1.2 meters/second. at what horizontal distance from the base of the table will the pen land?

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?

How can waves travel through ground?
