Decide whether the statement makes sense. Explain your reasoning.Our utility company charges 10 cents per joule for the energy we use.
What will be an ideal response?
Does not make sense. The units are fine, but the magnitude is ridiculous. A regular 100-watt bulb consumes energy at a rate of 100 joules per second. If the utility charged 10 cents per joule, it would cost $1 just to keep a 100-watt bulb on for a single second. That's $86,400 a day! (Explanations will vary.)
