Charge is a basic property of matter that creates a force and accounts for electric
interactions. Some particles and atoms have no
charge, so they are neutral. Is the atom in Figure 1
neutral or charged?

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?
