What kind of habitat do we live in

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz.

What is the speed of an object at a given moment?

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?
