Acircuit consists of a parallel-plate capacitor, an inductor, and a switch, which is initially open. the capacitor plates have an area of 1.00 × 10−4 m2 and are held 0.100 mm apart by a thin layer of barium titanate. the capacitor is charged to a potential difference of 14 v , and then the switch is closed. how much charge remains on the capacitor at the instant the energy stored in the inductor has increased to 80 % of its maximum?

An ice-making machine inside a refrigerator operates in a carnot cycle. it takes heat from liquid water at 0.0 degrees celsius and rejects heat to a room at a temperature of 19.2 degrees celsius. suppose that liquid water with a mass of 76.3kg at 0.0 degrees celsius is converted to ice at the same temperature. take the heat of fusion for water to be l_f = 3.34*10^5 j/kg.how much energy e must be supplied to the device? express your answer in joules.
