Homework with Hooke's Law
Wednesday--Feb 06, 2008 Filed in: 233
As many
of you have already realized, there is a mistake in
the textbook excercise # 5. You should use equation
8.4 (Hooke's Law), not equation 8.5. This question is
very similar to 3 & 4. Also, while I'm on the
topic of Hooke's law, let me point out that the
masses in the equation refer to the mass of a
single atom. The most
common error is to use molecular weights, rather than
atomic masses. You can find atomic mass by dividing
the molar mass by Avogadro's number.
