What energy also increases as mass increases

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?

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt

Does heating a metal wire increase or decrease its electrical resistance? why?
