The relative weight of each problem is indicated next to the problem number.
Most credit will be given for algebraic work. Please do not insert numerical values until
you have a final algebraic answer inside a box. If you don’t know a particular constant,
use a symbol to get partial credit. It is almost impossible to award partial credit if you
insert numbers too early. If you get stuck on one problem, go on to the next and come
back to the difficulties later in the exam period. Do not leave early until you have
completed everything. Do not quit! Never, never, never quit!!
As usual, before you start to manipulate equations and numbers you should
think for a
moment
and make sure that you have a general sense of the important features of a
problem. Also, once you have computed something, check to see if your answer has the
right units, and if it is in the right ballpark. For example, if your answer to any problem is
something like
π
x 10
418
Kelvin/meters, you should check your work.
