Damon is a musician playing in a band. At the end of a song, he plucks a single guitar string. The string moves rapidly back and forth as shown in the figure below.

Which of these statements explains what happens to the kinetic energy of the moving string? F. The kinetic energy is changed into potential energy and stored. G. The kinetic energy is converted to sound energy and thermal energy. H. The kinetic energy is slowly destroyed until no energy remains. I. Some of the energy is converted to sound energy, but the rest is destroyed.

The kinetic theory of matter states that all of the particles that make up matter are in a fix position.

The diagram shows Niels Bohr's theory about how electrons are arranged in atoms. He thought electrons traveled on specific paths around a nucleus. The current theory is that electrons exist in certain cloudlike regions around a nucleus. How would a model of the current theory differ from Bohr's model? A. It would be the same as Bohr's model. B. Object A would differ from Bohr's model. C. Object $B$ would differ from Bohr's model. D. Both objects $\mathrm{A}$ and $B$ would differ from Bohr's model.
