an unlabeled hierarchical diagram of various astronomical bodies is shown below. the labels a, b, c, and d can be used to represent the milky way, universe, planets, clusters, and stars.
an image of four circles nestled one within the other is shown. the lower boundary of all four circles touch one another. the largest and the outermost circle is labeled a. the next circle in order is labeled b. the next circle is labeled c. the innermost circle is labeled d.
part 1: which four astronomical bodies would you choose to represent the four labels in the diagram?
part 2: justify your choice based on the hierarchical relationships in astronomical bodies.

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?
