An electric 50 L hot water tank is initially full and has a temperature of 90 degrees C. Water is drawn from the tank at a rate of 0.08 kg/s. The shower is used for 10 minutes (cold and hot water are mixed). After the shower the water in the tank is now 70 degrees C. If cold water at 20 degrees C enters the hot water tank at the same rate as hot water exits, how much electrical work is done to the water in the tank?
