A proton is projected in the positive x direction into aregion of uniform electric field E = -6.60 multiplied by 105i N/C att = 0. The proton travels 7.40 cm as it comes to rest. (a) Formula for calculating the value of the acceleration (a) of theproton is
a = Eq / m
= -(-6.60 multiplied by 105i N/C)(1.6*10-19C) /(1.67*10-27kg)
= -6.32*1013m/s2i
So magnitude of the acceleration of the particle is a =6.32*1013m/s2
And its direction is alongnegative x direction
(b) Distance (S) traveled =7.40cm = 0.074m
Then we know the formula v2 - u2 = 2aS
0 - u2 = 2aS
= 2(-6.32*1013m/s2)(0.0740m)
u = 3.1*106m/s
So initial speed (u) of the proton is u = 3.1*106m/s
(c) Now time taken is t = u / a
= (3.1*106m/s) /(6.32*1013m/s2)
= 0.484*10-7s

Which statement best describes copper? a. it has a low resistance and prevents charges from moving freely. b it has a high resistance and allows charges to move freely. c. it has a high resistance and prevents charges from moving freely. d. it has a low resistance and allows charges to move freely

In a stagnant pool of water, a crayfish may spend much of its time lying with one side of its carapace near the surface of the water. in this position, it will move the walking legs on that side in a rhythmic back-and-forth motion. explain the likely function of this behavior.

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?
