3/178 The rigid assembly which consists of light rods and two 1.2‐kg spheres rotates freely about a vertical axis. The assembly is initially at rest and then a constant couple M = 2 N · m is applied for 5 s. Determine the final angular velocity of the assembly. Treat the small spheres as particles]

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?
