The 31-MV AC electricity from a power transmission into the primary ratio of the number of turns in the secondary coil to the number in the primary is N, INp 95 line is fed oil of a transformer ne 50%Part (a) what is the voltage, in megavolts, of the output from the secondary coil ofthe transformer? Part (b) The result from part (a) is much too high, well above the breakdown voltage ofair over reasonable distances (at a megavolt per meter). Which assumption is unreasonable and responsible for this engineering error?

Consider a double atwood machine constructed as follows: a mass 4m is suspended from a string that passes over a massless pulley on frictionless bearings. the other end of this string supports a second similar pulley, over which passes a second string supporting a mass of 3m at one end and m at the other. using two suitable generalized coordinates, set up the lagrangian and use the lagrange equations to find the acceleration of the mass 4m when the system is released. explain why the top pulley rotates even though it carries equal weights on each side.
