Cost of electricity varies but typical values are around $0.15/kWh. Using this price, calculate the cost of
(a) running a load of laundry through a dryer that takes 42.0 min and draws 5,300W,
(b) making a piece of toast in 3.00 min with a 980W toaster, and
(c) leaving a 50.0W light on for two weeks.
(d) For each of the previous cases, calculate how high you could lift your textbook that weights 3.5lbs if the process to convert the energy was 40% efficient.
(e) For each of the cases in parts (a) through (c), how much water could you vaporize? For full points, please clearly show all of you work so that I can learn how to do it. Thanks!
