Review | Constants Part A A Nichrome heating element that has resistance 29.0 S is connected to a battery that has emf 96.0 V and internal resistance 1.2 $ . An aluminum cup with mass 0.130 kg contains 0.200 kg of water. The heating element is placed in the water and the electrical energy How much time does it take for the temperature of the cup and water to rise from 21.2 . C to 34.5 . C? (The change of the resistance of the Nichrome due to its dissipated in the resistance of the heating element all goes into the temperature change can be neglected.) cup and water. The element itself has very small mass. Express your answer with the appropriate units.
