Homework Help: Quick Thermal Dynamics Question

  1. Jan 26, 2005 #1
    So we had a "quick quiz" a while back and I forgot about it and completely bombed it. I understand everything I did wrong now except for one part... Here's the question:

    Originally I just used:

    ...that wasn't taking into account the time it takes to go "tick-tock" and I'm pretty sure it was the wrong equation.


    So how should I go about this and why?

    Thanks!
