1. Report the H and b values you measured with uncertainty. Calculate the average range you actually measured (average position of all trials), as well as its uncertainty. Report the mass of the ball with its uncertainty. Show all calculations. Explain the source of uncertainties for any values that do not require calculation. 2. Use the H and b values with uncertainty to calculate the predicted range and its uncertainty in meters. Show your work. Compare your predicted range to your measured range: are they consistent? Can you determine whether energy has been lost on the ramp? Explain.
3. Assume that the energy lost was entirely due to friction and that the total length of the PVC pipe is 1 meter. Use this length to compute the average force of friction (ignore uncertainties).

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.
