An electron and a proton are separated by 2.4 nm
part a) What is the magnitude of the force on the electron?
Part b) What is the net force on the system?
A steady torque of 23-N•m is applied to a grindstone whose moment of inertia is 0.130 kg•m2. Using energy principles, and neglecting friction, determine the angular speed after the grindstone has made 13.0 revolutions.
A 480g , 8.00-cm-diameter solid cylinder rolls across the floor at 1.50m/s. What is the can's kinetic energy
A 70 kg man (rad=0.25m) standing on a 10-kg disc (rad=0.4m) with his arms extended (rad=0.9m) holding a 15-kg weight in each hand. What is the rotational inertia of man with weights.
Conservation of energy tells us that energy cannot be created or destroyed. Clearly, energy is required for radioactivity to occur. Where is this energy coming from?
