Railroad tank car is derailed and ruptured. it discharges 380 m3of pesticide into the mud lake drain. the drain flows into mud lake which has a liquid volume of 40,000 m3. the water in the creek has a flow rate of 0.10 m3/s, a velocity of 0.10 m/s, and the distance from the spill site to the pond is 20 km. assume that the spill is short enough to treat the injection of the pesticide as a pulse, that the pond behaves as a flow balancedcstr, and that the pesticide is nonreactive. estimate the time it will take to flush 99 percent of the pesticide from the pond.

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?
