Me! an ellipse is a type of oval shape. each planet's orbit is at a different distance from the sun than the other planets' orbits. beginning nearest to the sun, the order of the planets is: mercury, venus, earth, mars, jupiter, saturn, uranus, neptune. based on this order, which of the following is true of mars? a it must travel farther than earth does to complete one orbit around the sun. b it travels the same distance as earth does to complete one orbit around the sun. c it travels a shorter distance than earth does to complete one orbit around the sun. d it must travel in the opposite direction around the sun than earth does.

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?

Two 2.0-cm-diameter disks face each other, 1.0 mm apart. they are charged to ±10 nc. what is the electric field strength between the disks? a proton is shot from the negative disk toward the positive disk. what launch speed must the proton have to just barely reach the positive disk?

Notice how they put future which of the clouds shown would indicate a possible future rain storm? a) b) c) d)
