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

Astudent looks at ocean waves coming into the beach. an ocean wave with more energy will a) have a greater height. b) have a greater period. c) travel toward the beach faster. d) strike the beach with greater frequency.

What is the power rating of the lightbulb if 3.0 a flow through it when connected to a 15 v battery

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
