Which is one characteristic shared by electromagnetiic and mechanical waves

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

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                                         : )
