4. The rhododendron is a thermotropic plant that can respond to decreases in temperature by curling its leaves. This behavior most likely benefits the plant's leaves by

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?
