    I don't know much about pendulums, but I think you had a few pendulum problems yesterday. Did you see that equation?

    Yep! Haha! \[T=2\pi \sqrt{\frac{L}{g}}\] That equation is the only reason I can answer this equation. If I understood pendulums, I'd help you out with that. There, mathematically, the PERIOD is a function of the *length of the cord* and gravitational acceleration (which depends on *gravity*).

    Sometimes, if you know nothing else, you can look to the equations. Especially if it's a test and the equations are given somewhere. So learn what the variables mean, and a little bit to understand them :) It'll probably help more than once.

    In more than one way, too.

    oww okay so in the formula when you have it set up and you do everythin right at the end whatever you get last is the period right or no

    Well the \(T\) is the variable that is the period. In that equation, it is a function of ("dependent on") both the length of the cord, and gravitational acceleration.

    So there is no rearranging involved!

    Really, I never told you outright.. Just directed you to the math! And showed you it. You put that together.
