    Tension = Force Rule for calculating the force down the slope is Wcos(teta) for calculating the force above the slope is WSin(teta) so the tension in the wire is up the slope so you'll use the formula Force(tension) = WSin(teta) = W=weight = (450 x 9.81 x sin(12) ) = 917.8+640(as frictional...

    strange question o_O okay here goes remember that maxima and minima are formed at alternating points for e.g if n=1 is maxima then n=3,5,7 can only be used for the n values the angle and grating are the same so dsinO is a constant and nλ should be equal to it so just put in the n values in that...
