Physics

This assignment requires extensive research to collect info/scientific data that address the following questions (but not limited to) regarding the trend of global temperature change and its causes and impact. You must use sufficient scientific data (in the form of graph, chart, table, or external URL that connects to simulation or other forms of multimedia reference) and at least two detailed specific examples to address each of the following items. Your essay must address item #1 plus at least one more (or multiple) items from #2 to #6.  Item 1: a) Greenhouse gases-list major greenhouse gases and their percentage presence in earth atmosphere. b) Greenhouse Effect-explain the physical principles behind Greenhouse Effect and its pros and coms. c) List the data collected over last 100 years average temperature change (ocean, air and land) vs increase of greenhouse gases in earth atmosphere. Item 2: Select at least six satellites (currently on earth orbit sent by NASA/or European Space Agency) that monitor the greenhouse gases in earth atmosphere. a) List the info of each satellite: for example, its weight, launch date, altitude (height above the earth surface) and period, source of energy. b) Explain how each of these satellites detects and identifies the greenhouse gases (equipment on board the satellite and scientific methods used). c) List the data that has been collected so far from each satellite. Item 3: a) List top ten countries that are the major global greenhouse gases contributors and analyze the  sources of these greenhouse gases in each of these countries. b) Pick one or two countries among the ten that you listed, to discuss the impact of increasing greenhouse gases to its environment, for example: i) fresh water supply, ii) fishery, iii) agriculture, iv) wild animal life. Item 4: Pick one or two countries among the ten that you listed, to discuss the impact of increasing greenhouse gases to its social environment, for example: a) Health issues and disease control, b) Economy. Item 5: List major evidence of global climate change and its impact in one/or more than one of the following areas: a) ocean temperature and its ecology. b) polar ice cap condition and sea level change. c) sever weather patterns. d) shortage of food/fresh water supply. Item 6: a) Explain the core principles and measures of the Paris Agreement. b) Propose policies that you think that would mitigate greenhouse gases emission. c) Individual’s responsibility and effort that could contribute to slow down, or even reverse this potentially devastating trend of global climate change. The format requirements for this essay are: minimum of 4 full pages of text; margin no more than 1″ on the top, bottom, left and right; single line space; size 12, font TIMES. Please include a list of references at the end of the essay (beyond PAGE No. 4). Space used to present Graphs, photos and data tables is additional on top of the 4 full pages of text requirement..

All answers should be around 75 words long. No citations needed. 1) Identify one or two applications that depend on friction and air resistance.  Explain how friction or air resistance works in those situations and what would happen if there were no friction or air resistance.   2) In the first and second week of the course you learned to make kinematic calculations for free-falling objects and objects with two-dimensional motion.  This week you learned that you could solve similar problems using conservation of mechanical energy.  Give two examples where using conservation of energy to solve a problem is easier than the methods you learned earlier in the course.  Explain how you would use energy to solve the problem and why it easier. 3) A common demonstration in physics class is that of a bucket of water spun around in vertical circle. Explain why the water remains in the bucket during this demonstration.  Is there a minimum speed that the bucket must be spun for this work?  What is a practical application of this phenomenon? Your initial post should be 75-150 words in length and is due on Sunday. 4) Give two examples of Bernoulli’s principle in action.  Explain in detail how Bernoulli’s principle works in each situation. 5) Describe one tool or instrument, other than a thermometer, that works using the principle of thermal expansion.  Then give an example of a problem that is caused by thermal expansion and how it might be mitigated. 6) You learned about thermal processes in gases.  These included isobaric process (constant pressure), adiabatic processes (no energy is transferred between the system and surroundings), isovolumetric processes (constant volume) and isothermal processes (constant temperature).  Pick two of these thermal processes and give a real-world example of it.  Explain if there is heat transfer or work done in either case. 7) Describe one or two practical applications of the Doppler effect and explain how the change in frequency is used in each case to provide information or solve a problem.

Which topic or piece of information in each Chapter did you find most useful for future practice? Which is identifying and recongnizing signs of abuse as well as the importance of knowing the phases of treatment for clients Discuss Equilibrium Maintenance Vs Disequilibrium and select one of the cases to discuss (288-289) Discuss the importance of Realignment of generalizational boundaries and why its important for family treatment.

Motivation Insert Catchy Proposal Title Here • An opening paragraph that sets up the problem and your solution. Grab your fellow classmates attention and tell them why this is an important open problem in astrophysics and how your observing program will either uniquely solve this problem or improve our understanding. Background • The current state of knowledge about your science goal. Set up the big picture here about what we already know, as well as what we don’t yet know or understand. Science Goal(s) • Explicitly state the science goal(s) of your observing proposal in the context of the motivation and background. Technical Justification An explanation of how your proposed observations will reveal what you want to learn Motivate your choice of both the telescope and the instrument you need. What wavelength of the electromagnetic spectrum do you need to observe in? Imaging or spectroscopy? If you need to time monitor your object, explain and justify your observing strategy. Integrate the results of your supporting calculations relevant to your project into the technical justification to motivate the above choices (but list the full details in the appendix) Conclusions • A concluding paragraph to summarize the proposal’s key components References • References to the literature. If you use information from Wikipedia on your object, be sure to cite the original source (listed at the bottom of the page). Figures Images and figures to visualize your object and science topic. These are sometimes more effective if you mix them in with the text. Make sure you reference the Figures within the science justification, and include figure captions. Appendix • Full derivation of your supporting calculations, including the equation, units and math.

Identify a current problem in physics by searching for news articles and current events. One reputable source of news in physics is Phys.org. Choose one article, and in two pages, describe how the scientific method is being used to solve the problem mentioned in the article. Identify the initial observations that identified the problem, the hypothesis, tests, and any revisions of the original hypothesis. Paper must use at least one source, use proper spelling and grammar, and follow APA format.
