A 0.800 m long solenoid is formed by wrapping 600 turns of wire around a hollow cylinder with a radius of 0.260 m. At the instant when the magnetic field in the interior is 0.830 T, calculate the energy stored in the field.
A cylinder of radius 2.59 cm and a sphere of radius 7.97 cm are rolling without slipping along the same floor. The two objects have the same mass. If they are to have the same total kinetic energy, what should the ratio of the cylinder\'s angular spe..
