Hel Write responses to the following questions that assess your motivations in different situations. What activities do you do a lot because you enjoy them? What makes the activities enjoyable, and do you get anything out of the experience? What activities do you do a lot that you don't enjoy? (These might be chores or responsibilities you can't get out of.) Why do you still do them? How do you motivate yourself to get through it? Why do some hobbies appeal to you but others don't? Which school subjects do you find fascinating to learn about and which ones bore you? Are there any subjects that make you feel some anxiety to learn about or electives you try to get out of taking? What is it about these subjects that motivate you to do well or avoid them? What kind of grades do you get in your classes? Do you put in the maximum or minimum effort? Why do you do it that way? Are there expectations you perceive and what are they? How do you reward yourself for doing something hard? What inspires you to do a good job? How do you like people to reward you?

Some material consisting of a collection of microscopic objects is kept at a high temperature. a photon detector capable of detecting photon energies from infrared through ultraviolet observes photons emitted with energies of 0.3 ev, 0.5 ev, 0.8 ev, 2.0ev, 2.5ev, and 2.8ev. these are the only photon energies observed. (a) draw and label a possible energy-level diagram for one of the microscopic objects, which has four bound states. on the diagram, indicate the transitions corresponding to the emitted photons. explain briefly. (b) would a spring–mass model be a good model for these microscopic objects? why or why not? (c) the material is now cooled down to a very low temperature, and the photon detector stops detecting photon emissions. next, a beam of light with a continuous range of energies from infrared through ultraviolet shines on the material, and the photon detector observes the beam of light after it passes through the material. what photon energies in this beam of light are observed to be significantly reduced in intensity (“dark absorption lines”)? explain briefly.
