A 10-9-F capacitor (1 nanofarad) is charged to 50 V and then disconnected. One can model the charge leakage of the capacitor with a RC circuit with no voltage source and the resistance of the air between the capacitor plates. On a cold dry day, the resistance of the air gap is 6x 10 2; on a humid day, the resistance is 7x100 2. How long will it take the capacitor voltage to dissipate to half its original value on each day? 13 On the dry day, it will take seconds. (Use scientific notation. Round to three decimal places as needed.)
