Which of the following actions would make a pulse travel faster along a stretched string? more than one answer may be correct. if so, give all that are correct. a. move your hand up and down more quickly as you generate the pulse. b. move your hand up and down a larger distance as you generate the pulse. c. use a heavier string of the same length, under the same tension. d. use a lighter string of the same length, under the same tension. e. stretch the string tighter to increase the tension. f. loosen the string to decrease the tension. g. put more force into the wave.

Apossible explanation for a set of facts that can be tested by further investigation is called

*drag each tile to the correct location in the sequence* the table shows chronological events in the life of our sun, a medium-sized star. place the missing events into the correct rows of the table.

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?
