Ray decides to paint the outside of his uncle's house. He uses a 4.0-m-long board supported by cables at each end to paint the second floor. The board has a mass of 21 kg. Ray (70 kg) stands 1.0 m from the left cable.
What is the force that the left cable exerts on the board?
What is the force that the right cable exerts on the board?
The coefficients of friction for plastic on wood are μs = 0.50 and μk = 0.40. How much horizontal force would you want to apply to a 4.0-lb plastic calculator to start it moving from rest.
When an atom emits a photon in a transition from a state of energy E1 to a state of energy E2, Evaluate this recoil energy for the n = 2 to n = 1 transition of hydrogen.
