If almost any system in stable equilibrium is slightly disturbed, it will then exhibit simple harmonic motion because 1. the change in potential energy is proportional to the cube of the displacement from the equilibrium position. 2.

Based on relative bond strengths, classify these reactions as endothermic (energy absorbed) or exothermic (energy released) endothermic B2+C2-->2BC A+BC-->AB+C exothermic AB+C-->AC+B A2+C2-->2AC A2+B2-->2AB

Explaining how momentum can cause motion an astronaut on a space walk floats a little too far away from the space station. without air to push against, he cannot paddle back. however, the astronaut is holding a hammer.

A one-piece cylinder has a core section protruding from the larger drum and is free to rotate around its central axis. A rope wrapped around the drum of radius 1.39 m exerts a force of 3.34 N to the right on the cylinder.
