A monochromatic beam of light is absorbed by a collection of ground-state hydrogen atoms in such a way that three different wave-lengths are observed when the hydrogen relaxes back to the ground state. What is the wavelength of the incident beam?
Two balls are approaching each other head-on. Their velocities are +9.60 and -10.8 m/s. Determine the velocity of the center of mass of the two balls for the following conditions. (Use the sign of your answer to indicate the direction.) (a) They h
A 4.00-m-long, 500 kg steel beam extends horizontally from the point where it has been bolted to the framework of a new building under construction. A 70.0 kg construction worker stands at the far end of the beam. What is the magnitude of the torq
