Thanks to all of you who have have submitted help for other students here. I know a lot of people have contributed. It's been a good year.

For those of you continuing on to Physics 3, that board has freshly been put up at http://4ch4n.org/phys3/

As a reminder, there are boards for all of Chem 1, all of Math 3, and Physics 1-3. If you'd like any more, just post about it in /r/ (requests).

(2000-1260)/n/(5R/3)=t=-10.68
135-10.68=124.31
