Two students are studying for a Science Test. On the table they had a glass of water and identical cell phones. Both of their phones had run out of battery, therefore they were both charging in the same wall outlet. One student’s charging cord was 3ft and the other student’s charging cord was 9ft. The cell phone vibrated while ringing and knocked over a half-full glass of water. Using this scenario, answer the following questions. Part A: What energy transformations take place from the outlet charger to the ringing phone?

Part B: Explain how the Law of Conservation of Energy applies to the energy transformations that occur from the outlet charger to the ringing phone.

Part C: Predict which of the phones charged the fastest using Ohm’s Law. Cite evidence to support your theory.

Part D: Argue that the amount of water in the glass affects whether it falls over or not. The glass that fell over on the student’s table was only half full. Answer using 1st & 2nd Law of Motion to support your claim.
