A lunation is the period of time it takes the Moon to go from new to full and back to new, also called a lunar month.

The star is rapidly brightening. Some of the light gets reflected off interstellar clouds surrounding the object and sent our way. Despite what it looks like, most of the illuminated clouds we see there are actually behind the star, which causes the apparent rapid expansion.

so, is that a no?
What is an orbit or lunar month?

A speedy lunation

Let's say 'yes'

Consider a system of one particle in equilibrium with a heat bath. The particle has two microstates of energy <span class="math">e_1=0[/spoiler] and <span class="math">e_2=\Delta<span class="math">. find the probabilities Missing argument for subscript1 and p2 for the mean energy of the system to be .2\Delta, .4\Delta, .5\Delta/, .6\Delta, and \Delta, respectively. What are the corresponding temperatures? (hint: Write the mean energy as x\Delta and express your answers in terms of x.)

What does this even mean? How are there two probabilities? Can anyone give me some direction? I've read the chapter a few times.[/spoiler][/spoiler]
