Welcome to PHY 121 Blog Help. Here's how it works. For each homework question and lab report we will make a post, this will probably contain a few tips on what the problems are about and how to solve them. If you are stuck on something then instead of emailing us directly you should post a comment in reply to the relevant post. We will try to guide you through tough points and help you understand the problems and the concepts behind them.

I cant see the figure on my computer is it needed to solve the problem?
Can somebody help me on where to start with this one or explain it a little better? I am lost!
I have no idea how to complete this problem. I did every other problem and i've tried multiple ways to complete even the first part of #7 but everything I get is wrong. Even if the figure was there I think it would help because that'd how I understood #6, but I cant see the figure either.
Re all:
The figure is a picture showing how d is defined , namely from one leading edge of the tape to the next leading edge, not really needed at all to do the question. (It is posted in the Blackboard announcements now for completeness).
Write down equation (1.3): Delta(ax)/(ax)=Deltax/x and identify "a" in v=(1/t)d here. ((1/t) is assumed to be error free and thus is treated as a constant.)
Since (1.3) gives a relative error you have to convert it to an absolute error using (1.4)
