10) einstein’s famous equation indicate that e = mc², where c is the speed of light and m is the object’s mass .give this, what is the si unit for e?
11) express each of the following as indicated:

b) 2 h 10m expressed in seconds
c) 16 g expressed in micrograms
e) 0.675 mg expressed in grams
f) 462 um expressed in centimeters
g) 35/h expressed in meter per second

What is the role of the ocular lens?

What is the momentum of a 2 kg object moving at 15 meters per second

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.
