Textbook Question
Chapter 12, Problem 8QQ
Choose the best answer to each of the following. Explain your reasoning.
Why do virtually all the galaxies in the universe appear to be involving away from our own? (a) because we are located near where the Big Bang happened (b) because we are located near the center of the universe (c) because observers in all galaxies see a similar phenomenon due to the universe’s expansion

Read the following questions carefully and answer the problems using GRESA.
1. Assuming that the field of view is flat, what is the resultant vector (yellow line) of an observer pointing his telescope starting at the Andromeda galaxy, then moving 62 units 27° S of W to Jupiter, then finally moving to Saturn 17 units 72° S of W. Express your magnitude to the nearest hundredths units, and the angle to the nearest hundredths °, following the standard cartesian plane coordinate system.
State the definition for a parsec, and derive its value in terms of As- tronomical Units. Convert your answer for the value of the distance of a parsec in Astronomical Units into light years. Be sure to include a large and clearly labeled diagram showing how you arrived at your conclusions. Be sure to show all work!
