In an rl series circuit, an inductor of 3.54 h and a resistor of 7.76 ω are connected to a 26.6 v battery. the switch of the circuit is initially open. next close the switch and wait for a long time. eventually the current reaches its equilibrium value. at this time, what is the corresponding energy stored in the inductor?

1. jay fills a wagon with sand (about 20 kg) and pulls it with a rope 30 m along the beach. he holds the rope 25° above the horizontal. the rope exerts a 20-n tension force on the wagon. how much work does the rope do on the wagon?

Asolid cylinder and a cylindrical shell have the same mass, same radius, and turn on frictionless, horizontal axles. the cylindrical shell has light-weight spokes connecting the shell to the axle. a rope is wrapped around each cylinder and tied to blocks of equal masses that are held the same height above the ground. both blocks are released simultaneously. the ropes do not slip. which block hits the ground first? or is it a tie?
