Given that the collision is completely inelastic and Glider 2 is initially at rest (2, = 0), please show that the energy loss rate always satisfies |K,1+K,2−K,1−K,2| |K,1+K,2| = m2 m1+m2 (hint: find the kinetic energies in terms of 1, and use them to compute the loss rate). Explain how this relation tells that the energy is not conserved upon a completely inelastic collision

What is the energy of a photon of ultraviolet radiation with a frequency of 4.4 × 1015 hz? planck’s constant is 6.63 × 10–34

The slope of a velocity time graph over any interval of time gives the during that interval

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?
