An experiment begins with crystalline salt at the bottom of an otherwise empty glass. first, students add water to the glass. then they mix the solution until the salt crystals dissolve completely. rate the entropy of the water-salt system during this process from highest entropy to lowest entropy. group of answer choices

a. the entropy of the system shortly after mixing begins > the entropy of the system after the salt dissolves completely > the entropy of the system right after adding the water
b. the entropy of the system after the salt dissolves completely > the entropy of the system shortly after mixing begins > the entropy of the system right after adding the water
c. the entropy of the system right after adding the water > the entropy of the system shortly after mixing begins > the entropy of the system after the salt dissolves completely
d. the entropy of the system after the salt dissolves completely > the entropy of the system right after adding the water > the entropy of the system shortly after mixing begins
e. the entropy of the system shortly after mixing begins > the entropy of the system right after adding the water > the entropy of the system after the salt dissolves completely
f. the entropy of the system right after adding the water > the entropy of the system after the salt dissolves completely > the entropy of the system shortly after mixing begins

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?
