Chapter 1, Problem 12P
Why is the following situation impossible? A student’s dormitory room measures 3.8 m by 3.6 m, and its ceiling is 2.5 m high. After the student completes his physics course, he displays his dedication by completely wallpapering the walls of the room with the pages from his copy of volume 1 (Chapters 1–21) of this textbook. He even covers the door and window.

Its wintertime and you are in need of portable electrical heater for your room and you are comparing two different products. The first heater has metal grills made of aluminum and has dimensions of 0.75 [m] x 0.05 [m] x 0.01 [m] while the second heater has metal grills made of iron and has dimensions of 1.00 [m] x 0.03 [m] x 0.01 [m]. You wish to heat your room from 10 degrees Celsius to a nice toasty 28 degrees Celsius and your wall outlet provides 120 [V].
A)What is the resistance of the aluminum and iron heater at 28 degrees Celsius?
B)What is the current for the aluminum and iron heater operating at 28 degrees Celsius?
C)If you wish to operate your heater for 4 hours and the cost of electricity is $0.12 per kilowatt-hour, which heater has cheaper operational costs?
