Consider the diagram shown at right, which has a 36 V battery connected to three resistors valued at R1 = 6.0 Ω, R2 = 12 Ω, and R3 = 18 Ω. Calculate:
a. the power dissipated across R1
b. the electric potential difference across R2
c. the total charge that flows through R3 every minute

Calculate the amount of heat produced when 18000 coulombs of charge is transferred in one hour through a potential difference of 50v

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.
