A meter stick has a mass of 200 g. It is balanced on a fulcrum at the 50 cm mark and there is a 100 g mass at the 100 cm mark. Where do you place another 100 g mass and keep this system balanced (at what reading on the meter stick)?
A)At the 0 cm mark.
B)At the 25 cm mark.
C) At the 50 cm mark.
D)At the 100 cm mark.

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?
