Chapter 11, Problem 22SEQ
Explain all answers clearly, with complete sentences and proper essay structure if needed. An asterisk (*) designates a quantitative problem, for which you should show all your work.
Weighing Supermassive Black Holes. Which of these devices would be a better tool for measuring the masses of black holes at the centers of other galaxies: camera that takes extremely sharp pictures or a Spectrograph that produces precise measurement of emission - line wavelengths? Explain.

ONLY ANSWER 3 AND USE OTHER QUESTIONS FOR CONTEXT
Suppose we have two sources of light, a deep red one with wavelength 700 nm, and a violet one with wavelength 400 nm. Both produce the same optical power, delivering 1 milliwatt (10−310−3 watts) of energy per second per square centimeter to a metal target with an area of 1cm2 located 1 meter from the sources.
1. Which color would deliver more photons each second?
All the photoelectrons that are produced from the light are presumed to be collected by another electrode and we determine the current in amperes using a circuit and an "ammeter", that is, some device that can give a precise quantitative measure of the current. Such a device might use the magnetic field generated by the current, or the voltage produced when the current flows across a resistance.
2. If the work function of the surface is 2 eV, will we see a current with both colors, one color, or neither one? If so, how much (in amperes), or if not, explain.
3. If we now…

Thank you so much. A space ship warp engine has enough energy to perform two warp jumps going between star systems (i.e., the warp battery has 2 units of charge). The ship can operate in two modes: survey the current system or charge battery. On a given day the ship will complete the survey of the current system with probability 0.24. Then, if battery has capacity, it will move to a new system, consuming 1 unit of charge. If the battery is empty, the ship will switch to the charging mode. In the charging mode, the ship will recover 1 unit of charge on a given day with probability 0.95. The ship will stay in the charging mode until the battery is full. Model the behavior of the ship as a Markov chain.arrow_forward
