8. “A person in a dark room looking through a window can clearly see a person outside in daylight, whereas the person outside cannot see the person inside. Explain.
This can be related to the angles of light from the room compared to outside. On the inside the interior setting is blocking the room from being illuminated by the sun, so the angles of light are limited to a spot close to the window. A person standing close to the window may be able to be seen, but if they go back then they will not be illuminated, and will not be seen. A person looking out can see clearly because there are no objects blocking the sun from illuminating the person and their soundings.

You are behind the spider, 50 cm from the mirror. Show that the distance between your eye and the image of the spider in the mirror is 70 cm.” When it refers to “the image of the spider on the mirror,” it is really asking for the distance between your eyes and the mirror. If a spider is 20 cm behind the mirror, and you are 50 cm away from the spider, then adding those two distances will give the total, which is 70 cm just as the problem says.
8. “The quantitative way of relating the object distance d-sub o with the image distance d-sub i for a lens given by the then-lens equation (1/d-sub o)+(1/d-sub i)=1/f. Rearrange to show that d-sub i=(d-sub o)(f)/(d-sub o)-(f)”
This is an algebra problem involving an equation with fractions. I solved it on paper and attracted the work, but it should be noted that I substituted d-sub o with a, d-sub i with b, and f with c. To briefly explain how I solved it, I did the following:
-found a common denominator of abc, which led to the two fractions on the left side being combined into one.
-canceled out ab/ab on the right side,
-cross-multiplied to get abc=bc^2+ac^2
-factored out c^2, then divided it by both

In Chaim Potok’s novel The Chosen, specifically chapter 9, Potok was able to symbolically delineate Reuven and Danny’s lives with a reference to a spider entrapping a fly. To start off, Potok introduced the spider in the allegory as Reb Saunders. When Reuven noticed what was going on near him, he recalled seeing the spider and saying, “A spider had spun a web across the corner of the upper rail, and there was a housefly trapped in it now… the spider, a small, gray, furry-looking spider, with long, wispy legs and black eyes, move across the web toward the fly” (Potok 173-174). Reb Saunders can be seen as the spider from mainly the physical characteristics of it as well as the actions. For example, when Reuven describes the spider having “black eyes” and “gray, furry-looking”, Reb Saunders falls under all of those features.
41. On a map with a scale of 1:50,000, the distance between point A and B is 18 centimeters. What is the actual ground distance in meters?
In response to your question from chapter 4 of Essentials, as a child my favorite book was Chica Chica Boom Boom by Bill Martin, Jr. and John Archambault. In addition to the catchy text, I think part of what made this book one of my favorites was the relatively simplistic illustrations that utilized bright, eye-catching colors that were visually appealing to me as a child. In my opinion, The Very Busy Spider is similar to Chica Chica Boom Boom in terms of illustrations. The Very Busy Spider utilizes a vast array of the color spectrum ranging from dark to light colors with a vivid orange and lime green for the spider. The illustrations are not overly detailed, so it does not distract the reader from the context of the story but rather
Throughout the novel Invisible Man, Ralph Ellison works with many different images of blindness and impaired vision and how it relates to perception. These images prove to be fascinating pieces of symbolism that enhance the themes of impression and vision within the novel. From the beginning of the novel when the narrator is blindfolded during the battle royal to the end where Brother Jack's false eye pops out, images of sight and blindness add to the meaning of many scenes and characters. In many of these situations the characters inability to see outwardly often directly parallels their inability to perceive inwardly what is going on in the world around them. Characters like Homer A. Barbee and Brother Jack believe they are all knowing
model distance=0.25 inches/1,391,900 km * actual distance in km. We used this formula to calculate the distance in which each planet lies from the Sun. We found the overall scale distance of each planet
Scaled radius of the Sun: 6.96 x 105 Km * (1 cm/6.96 x 104 Km) = 10 cm
4. Most of you did not have enough time to complete the redistillations of Fraction 1 and Fraction 3, but you are still equipped to anticipate the results.
If the formula for the circumference of a golf ball (the distance in inches around the outside of the ball) is 3 times the ball’s diameter, which of these numbers is closest to the ball’s circumference? 1 inch or 5 inches or 12 inches
1)The field of view in Figure 1-2 is a factor of 100 larger than the field of view in Figure 1-1. What aspects of Figure 1-2 increased by a factor of 100 relative to Figure 1-1? Did the height increase by that amount? The diameter? The area?
Find the average distance of Pluto from the Sun. Using the same scale as Procedure B, calculate the scaled distance that Pluto should be on your model. Show your work! 5,906,376,200 / 25,000,000 = 236.25cm ~ 236 cm
The act of looking is related to physical vision while the act of seeing involves an enhanced understanding of what it means to truly exist. In the short story “Cathedral”, the narrator is blind to appreciating the human experience until he meets a blind man who ironically becomes the one who teaches him how to see in a way he never knew how. The author Raymond Carver uses symbolism within this story to reinforce the theme of blindness, and the difference between looking and seeing.
Step 9: Because we measured the lengths in centimeters rather than meters, we need to calculate are ‘g’ value into m/s2 so we can compare it to the SI unit for acceleration due to gravity. (Eg. 981.4/100 = 9.81 m/s2)
