In answering the questions below, consider the transformer ideal unless otherwise noted. (figure 1) part a the primary coil of a transformer contains 100 turns; the secondary has 200 turns. the primary coil is connected to a size aa battery that supplies a constant voltage of 1.5 volts. what voltage would be measured across the secondary coil?

If an object with an initial temperature of 300 k increases its temperature by 1°c every minute, by how many degrees fahrenheit will its temperature have increased in 10 minutes? (a) 6°f (b) 10°f (c) 18°f (d) 30°f

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.
