You think you might have mixed your salt (NaCl) up with naphthalene (C10H8). You know that NaCl is safe to eat, but C10H8 is very dangerous. You need to find out which one is which before you put it on your lunch. Design an investigation in the space below that will help you determine which substance is NaCl and which one is C10H8.
How will you determine which substance is NaCl and which one is C10H8?
Explain why you think this will work.

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

In this thread, i would like you to comment on the nature of light and how operation of telescopes. light has a duality of a particle and a wave; which one affects your life? also how does light interact with optics inside telescopic systems? answer these questions in two paragraphs. then respond the another students response.
