*SIMPLE slope question on graphic - Units?

  1. Jan 29, 2012 #1
    1. The problem statement, all variables and given/known data

    I just want to be 100% sure I got this correct.

    I have a log graph, and along the x axis I have diameter (in cm's) and up the y-axis I have period (in seconds).

    I had to get the slope, which I got, but what are the units of the slope?

    s/cm ???



    2. Relevant equations



    3. The attempt at a solution

    Let's see ... you waited 2 hours and 32 minutes before bumping. That's about 21 hours and 28 minutes short of what's required.

    Which axis is a logarithm? ... or are both?

    hi nukeman! :smile:

    a log is always dimensionless

    even when it looks as if it's eg log(time), it's really log(time/time0)…

    dimensionless! :wink:

    so the logx (or is it logy?) axis has no units :smile:
