A square loop of edge a having `N` turns is rotated with a uniform angular velocity `omega` about one of its diagonals which is kept fixed in a horizontal position. A uniform magnetic field `B` exists in the vertical direction. Find (a) the emf induced ion the coil as a function of time `t` (b) the maximum emf induced (c) the average emf induced in the loop over a long period (d) the average of the squares of emf induced over a long period  (e) if resistance of loop is `R` , amount of change flow in time `t=0` to `t=2T` (f) heat produced in time `t =0` to `=4T`
