Abucket of mass m is hanging from the free end of a rope whose other end is wrapped around a drum (radius r, mass m) that can rotate with negligible friction about a stationary horizontal axis. the drum is not a uniform cylinder and has unknown moment of inertia. when you release the bucket from rest, you find that it has a downward acceleration of magnitude a. what is the tension in the cable between the drum and the bucket?

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.
