Compare dalton’s atomic structure to Bohr’s

Living in South Florida has many advantages and also includes many disadvantages, including the persistent threat from hurricanes (https://www.c2es.org/content/hurricanes-and-climate-change/). From what you have learned from this class: What causes hurricanes? What destroys hurricanes? What are scientists saying about the link of climate change and hurricane activity? With regards to our growing population, especially along the cost, why are we especially prone to huge losses when a hurricane hits? With regards to hurricanes and South Florida, if you were in a position to grant or deny building permits, what would be your chief concern when assessing these permits? Make sure to: Write a short essay or paragraph of at least 300 words (worth 80/100 points).  Use concrete examples/details and avoid generalities.

Impact of aeroanutics re-engineering in military forces

Question 1)                             80 Points                                 ~ 200 Words What are the differences between the Apparent Magnitude m, and Absolute Magnitude M ?  The brightness of an object depends on its distance in what way,  i.e. what is the term for this mathematical relationship?  From what distances are m & M determined?  Compare M  to the Luminosity L, which does not depend on distance. How are they similar?  If you take the difference of the Apparent Magnitude and Absolute Magnitude, i.e.  m – M = X,  what important quantity can you determine?   What is a “Standard Candle”?   Question 2)                             40 Points                                 ~ 100 Words Discuss the Hertzsprung–Russell diagram.  What types of variables are plotted on the horizontal and the vertical axes of the diagram?   What are the four main regions of the diagram,  and what kinds of stars are found there?  Why is the H-R diagram so useful in Astronomy?   Question 3)                             80 Points                                 ~ 200 Words For a star to be on the Main Sequence of a Hertzsprung–Russell diagram, what nuclear fuel must it be “burning” in its core?  Main Sequence stars must also be stable. This is known as Hydrostatic Equilibrium.  What are the two forces involved in Hydrostatic Equilibrium?  How does the Mass of a MS star effect its temperature, and hence its lifespan on the Main Sequence?  Compare the Main Sequence lifespans of a red dwarf star, a yellow star like our Sun and a blue giant star.  What happens to a star when it leaves the Main Sequence?  What are the two end results for a star when it exhausts its nuclear fuel,  and how does it depend on the star’s Mass?

You will write a research paper on the possibility of life on a particular world; this can be a planet or moon in our solar system, or an exoplanet. After selecting a potentially habitable world and having it approved by your instructor, you will critically analyze the possibility that life exists there. The research will involve selecting several different published studies and synthesizing the results from these studies to arrive at your final assessment.

Subject is GMO’s in agriculture • Describe the diffusion of a contemporary innovation in the agricultural and natural resources context . Evaluate how the attributes of the innovation and adherence to the diffusion process affected its diffusion and the ultimate success or failure of the innovation? . All references should be listed in a reference section at the end of the paper; be sure to use APA 6 th Edition formatting. The reference page does not count as part of the page length.

Your final project presentation will be focused on a topic that you select from the NASA Science, Solar System Exploration website. You can find the link in Unit 8 directly below this assignment tab.
