Question 3: a) In the Mathematical Insight chapter 1 section 1.1 page 9 show us how to calculate the distance of light year. And we also know that the light speed is constantly 300,000 km/s. b) My calculation has only 8 digits, so couldn’t use the number 300,000 so I put 30 instead. After calculated, I forgot to put the 4 last 0 to the result. So I got completely wrong answer. c) A question at the end of chapter 1, Problems 19 Distance by Light page 24 is related to this question. Question 4: a) Figure 1.1 page 5 chapter 1 section 1.1 shows the images of our place in the Universe. So we can know the order of things in Universe b) I was confused about the Local Supercluster and Local Group, because I know the shape of the Galaxy, or how the stars system look like. But the supercluster or the group is just the same as universe, no shape at all. So I thought it was a part of the galaxy which include many stars systems. c) This question is the same with question A in the Conceptual Quiz chapter 1. Question 10: a) Chapter 1, section 1.2 page 10 the Scale of the Universe. We also talk about this in the very first day of class. b) It was my time have been to Blowing Green, it’s kind of hard to imagine how big the Blowing Green, even the WKU main campus. So I was kind of ignore that lecture. And I thought Pluto is very very far away from the Sun compare to other planets, and this question ask for its area, so I chose the size of BG, not big as Arizona , but not small like a campus. c) This question is relate to the question F Conceptual Quiz chapter 1. Question 12: a) Chapter 1, section 1.2 page 13 The scale of the Milky Way Galaxy. It tells the nearest star system to our own is 4.4 light-years. It says the Pluto is a short walk away, the distance to the nearest stars is equivalent to the distance across the US. b)
