These two waves travel along the same string: y1 = (4.17 mm) sin(2.24? x - 300? t), y2 = (5.96 mm) sin(2.24? x - 300? t + 0.727? rad). what are (a) the amplitude and (b) the phase angle (relative to wave 1) of the resultant wave? (c) if a third wave of amplitude 5.20 mm is also to be sent along the string in the same direction as the first two waves, what should be its phase angle in order to maximize the amplitude of the new resultant wave?

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
