Compute all givne parts of following question:

Question: Water has a latent "heat of fusion" of 334 kj/kg. in other words, making 1kg of ice from water at 0 degrees c requires 334 KJ of energy. Imagine you had 155g of ice at 0 degrees C. which you left on an electric oven coil. When you returned 30 seconds later, the temp of the water n the coil was 54 degrees C.

Part A: Assuming the burner had a voltage of 120 V across it and that the ice/water gained no heat from the atmosphere what is the resistance of the coil?

Part B: How many electrons passed through the coil in those 30 seconds?

Please show your results in detailed calculations.
