A typical AA battery has a potential difference of 1.5 V and stores 10,000 J of chemical energy. An electric fan powered by two AA batteries in series can be treated as a single resistor with resistance 15.0 Ω connected to the batteries. Assume the potential difference provided by the batteries remains constant until they completely run out of energy. Instructions In a neat and organized fashion, write out a solution which includes the following: If this fan is run continuously, how long will it take for the batteries to run out of energy? Clearly show all steps, starting from generalized equations. Explain your mathematical work in words. Your explanation should cover both what you did and the thought process behind why you did that. Evaluate your answer to determine whether it is reasonable or not. Consider all aspects of your answer (the numerical value, sign, and units) in your evaluation.
