30 points a girl out!   a political action group that wants to overturn the montreal protocol monitors stratospheric ozone across the south pole over a 10-year period. they compare changes in the ozone layer to increases in the average global temperature and find no correlation. because of this, they claim that ozone layer depletion is a myth. what is the major flaw in their reasoning? a. global warming is not observable at the south pole. b. only tropospheric ozone will correlate to global warming. c. the loss of stratospheric ozone is not connected to global warming. d. the effects of the montreal protocol will not be fully realized until 2050. e. ten years is too short a time period for meaningful data to be acquired.

When fat comes in contact with sodium hydroxide, it produces soap and glycerin. determine whether this is a physical change or a chemical change. explain your answer

What will a positive and a negative charge do if they are separated from each other?

5submission this assignment is worth 20 points total. you are required to submit the following by next lab: 1. (3 points) determine the equation for the output angular velocity ω2 = θ˙ 2 as a function of θ1, ω1 = θ˙ 1 and α. you must show all your work to receive credit. 2. (2 points) use the result of problem#1 to plot ω2 over 0 ≤ θ1 ≤ 360deg with ω1 = 360deg/sec. do this for α = {10,30}deg. show the results on the same plot and properly label the axes, title, legend. for this you can use matlab or ms excel. 3. (3 points) determine the equation for the output angular acceleration ω˙ 2 and create a plot similar to the one in problem#2. 4. (10 points) submit plots of the results (ω2 and ω˙ 2) obtained from creo/mechanism and compare them to results of problem#2 and problem#3. note that you should do these comparisons for the two cases with α = {10,30}deg. 5. (2 points) provide a brief explanation of the results. did they match? what are the implications as misalignment angle increases?
