You are studying a system that has five evenly spaced energy levels. The lowest energy level (labeled "1") has an energy of 0.5 J. The remaining energy levels (labeled 2-5 in increasing energy) are evenly spaced, with 1 J energy spacing between the levels There are three particles in the system, and any number of particles can occupy each of the energy levels. If the average energy per particle is 3.5 J, as in the four questions above, how can...

4.8 He-Ne Laser The He-Ne laser system energy levels can be quite complicated, as shown in Figure 4.58. There are a number of lasing emissions in the laser output in the red (632.8 nm), green (543.5 nm), orange (612 nm), yellow (594.1 nm), and in the infrared regions at 1.52 μm and 3.39 μm, which give the He-Ne laser its versatility. The pumping mechanism for all these lasers operations is the same, energy transfer from excited He atoms to Ne...

Using the script story.py as an example and possible starting point, write a script that generates a story using multiple levels of function calls that mirror the structure of your story. Your script must have the following requirements: At least two functions must have randomly determined elements. Your script must accept some form of user input (e.g. name of the hero), which is then used throughout the story. The function structure of your script must have at least four levels....
