Heat Capacity (car brakes, solar hot water) quiz

You are welcome to use your notes, but please do these problems on your own.  If you need help, go back to the teamwork papers and ask a friend or Mr. Shumway to explain something to you.  You are welcome to repeat for 100%.  If you get a higher score after I have entered a score, just let me know with an e-mail message, or a note in the physics tray.
