    my physics coursework is on resonance
    wat do i put in the variables and constants - i dont mean what do i actually write in them, but wat generally does that mean?
    also for error bars, to get the uncertainty for the horizontal error bar you do the biggest value - smallest and divide by 2. but wats the equation for the vertical error bar, or are they the same. my graphs, for the horizontal its the uncertainty of length, and the vertical is the uncertainty of the tension in the wire, so theyre not the same, but do they have the same equation to work it out? thanx.
