Astronomy HOMEWORK Chapter 1 9th ed 5. In Figure 1-8, what is another name for the “Sun’s annual path?” Ecliptic. This term also refers to the mathematical plane of Earth’s orbit. 10. By about how many degrees does the Sun move along the ecliptic each day? The Sun moves 360 degrees in 365.25 days along the ecliptic, so Degrees per day = (360◦ )/365.25 days = 0.986◦ = 1◦ . Round to 1 degree since the question says “about how many...” 14. What are the vernal and autumnal equinoxes? What are the summer and winter solstices? How are these four events related to the ecliptic and the celestial equator? The equinoxes are the points on the celestial sphere where the ecliptic and celestial equator intersect. The vernal equinox is the point where the sun crosses the celestial equator northbound.…
This episodes of cosmos was a very interesting one. Neil Degrasse starts off with what was suppose to be the means of diversity between humans and animals and he speaks on the topics of natural selection, genetic drift and more to explain why there are so many different breed of creatures and why some are preferred compared to others in certain types of environments. He introduced us to a tree that contained all of the creatures that have been discovered by man, and he tells us the similar physical features that are shared amongst ourselves and those creatures. The part that fascinated me the most is the one that spoke on the topic of the development of eyesight, he used the example of sea creatures to display the complexity of eyesight development.…
1. The parallax of the star 75 Leo is 0.10 and its apparent visual magnitude is +5.18. The absolute visual magnitude of 75 Leo is +5.14.…
My experience with this optional observation lab was a great experience overall, just as I had expected it to be. I was much more interested in participating in the observations versus sitting in a classroom every week and attending the labs like in 1010.…
6. Kepler’s second law is that a line that connects a planet to the sun will cause the planet to travel the same distance in the same time.…
A rising third-grade student named Ayden Pollard was chosen to participate in this assignment. The second-grade reading passage, entitled “The Night Sky,” was selected for Ayden to read. He appeared interested in the reading topic and read the passage quickly and fluently. Upon scoring this reading passage, Ayden used one mispronunciation, five substitutions, three insertions, and eleven omissions. According to Tompkins (2014), “only words that students mispronounce or substitute can be analyzed; repetitions and omissions are not calculated” (p. 85). Thus, omitted words were not included in the student’s reading level score. However, the high omission total is the focus of a key teaching point that should be addressed to increase overall reading…
-The sun is located in one of the Milky Way's outer arms, about 25,000 light years from the galactic center.…
1. Scientific thinking is our ability to use our prior knowledge and use the knowledge in finding answers to new knowledge. This differs from our everyday thinking because we probably wouldn’t be trying to acquire new information which scientific thinking we always are.…
Passage of shock wave induces shock metamorphism in the rocks and minerals of an impact crater…
F = ma where F is force, m is mass, and a is acceleration. This means that if you apply the same amount of force to two different objects with one mass larger than the other, the acceleration will be different.…
1) What do we mean by a geocentric universe? Contrast a geocentric view with our modern view of the universe.…
Q1) Last night you saw the star Betelgeuse exactly on your eastern horizon at 5:47 PM. Two students are discussing their answer to the question "At 5:47 PM tonight where will you see Betelgeuse?"…
The red planet Mars has long been a cultural and scientific fascination. People have pondered for decades over the biological potential of the planet and its past. Geological features on Mars resembling dry riverbeds, and the discovery of minerals that form in the presence of water, suggest that Mars once had a thicker atmosphere and was warm enough to allow liquid water to flow on the surface. But phenomenally, the Mars that is seen today is radically different --- barren, lifeless, and dry. Why? In hopes of uncovering the answers to these mysteries, the National Aeronautics and Space Administration (NASA) will launch its newest mission to Mars, the Mars Atmosphere and Volatile Evolution Mission (MAVEN).…
On the first day of spring, the Sun sets a) north of west b) directly…
Satellites orbiting the earth and other advanced technologies have enabled scientists to collect many different types of information about our planet and its climate on a global scale. This body of data, collected over many years, reveals the signals of a changing climate.The heat-trapping nature of carbon dioxide and other gases was demonstrated in the mid-19th century. Their ability to affect the transfer of infrared energy through the atmosphere is the scientific basis of many instruments flown by NASA. There is no question that increased levels of greenhouse gases must cause the Earth to warm in…
