Question 52





Q52: Why is the following situation impossible? A politician is decrying wasteful uses of energy and decides to focus on energy used to operate plug-in electric clocks in the United States. He estimates there are million of these clocks, approximately one clock for each per- son in the population. The clocks transform energy taken in by electrical transmission at the average rate W. The politician gives a speech in which he com- plains that, at today’s electrical rates, the nation is los- ing $100 million every year to operate these clocks.
