A solid cylinder of mass 12.0 kgkg and radius 0.250 mm is free to rotate without friction around its central axis. A) If you do 75.0 JJ of work on the cylinder to increase its angular speed, what will be its final angular speed if the cylinder starts from rest? Express your answer in radians per second.
B) What will be the cylinder's final angular speed if it is initially rotating at 12.0 rad/s?

Solar cell a produces 100 joules of energy, when a light source is shown on it for 3 minutes. solar cell b produces 200 joules of energy when the same light source is shown on it for 5 minutes. which solar cell works better? a) solar cell b, because it produces more energy. b) solar cell b, because it generates more power. c) solar cell a, because it produces energy quicker. d) solar cell a, because it generates a greater wattage. eliminate
