For the Ball Drop experiment, observe the graph of the vertical displacement of the small ballagainst time (yvs. t). What can you say about the vertical displacement of the small ball? Whatgraph shape is this? What does this shape tell you about the mathematical relationship between yand t?

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

explanation:

wire in brush may conduct electricity from cell to drill and vice versa electrc shock possible

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                                         : )
