Two capacitors have equal capacitance. The first capacitor is holding twice as much charge as the second capacitor. How much energy does the first capacitor hold relative to the second?.

If you visited mount shasta city (elevation 900 m [3000 ft.]) and found the outside air temperature to be 27°c (81°f), what would be the air temperature at the summit of mount shasta (elevation 4200 m [14,000 ft.]) at that moment-assuming that the temperature conditions with altitude change at an average, or normal, lapse rate?
