Around the core of a nuclear reactor shielded by a large pool of water, cerenkov radiation appears as a blue glow. cerenkov radiation occurs when a particle travels faster through a medium than the speed of light in that medium. it is the electromagnetic equivalent of a bow wave or a sonic boom. an electron is traveling through water at a speed 10% faster than the speed of light in water. (a) determine the electron's total energy. (b) determine the electron's kinetic energy. (c) determine the electron's momentum. (d) find the angle between the shock wave and the electron's direction of motion.

Ababy stroller is a rest on top of a hill which is 10 m high. the stroller and baby have a mass of 20 kg. what is the potential energy of the baby and stroller?

When you push downward on a book at rest on a table, you feel an upward force. does this force depend on friction? defend your answer.

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?
