I have this question on my Physics HW and I am having a little trouble. I think I may be making it more complicated than it is. Here is the question
A violin string vibrates at 294 Hz when unfingered. At what frequency will it vibrate if it is fingered one third of the way down from the end?

I am not seeing how where I "finger" the string is going to affect it. It doesn't seem to be explaining this in my book and I am taking this online. You don't have to give me the answer but some guidance on solving it would be great. Thanks in advance.

I'm presently taking Wellbutrin XL 300mg daily and don't feel like it does the job. But...I know Effexor is hard to quit taking once you've started. Is it worth the "addiction?"

State precisely what is meant by each of the following four terms. Then distinguish clearly between each of the two terms in part (a) and between each of the two terms in part (b) , using chemical equations or examples where helpful.

(a) Bond polarity and molecular polarity (dipole moment)

(b) For a metal M, ionization energy and electrode potential

This is not an attempt to bypass my homework responsibilities! This question featured in the June 2002 "Chains, Rings & Spectroscopy" Chemistry paper - Advanced GCE OCR (UK) which I completed as a mock exam recently. My tutor/teacher agrees with my suggested answer (I don't want to pre-empt your answers!) but is puzzled as to why the question was aimed at halogenated phenols instead of just general phenols. We do not have access to the relevant Mark Scheme.
