Below is shown a ray of light in air striking the side of a triangular prism, with an inde6 refraction =1.5. Reflect and refract the ray at the first surface, but only refract it at the second surface. Extend both the reflected ray from the first flat surface and the transmitted ray through the 2nd curved surface to show their point of exit from the page. There is no internal reflection going on here. Show any calculations you make somewhere on this page.

Two masses are connected by a string as shown. Mass $m_A$= 4.0 kg rests on a rough inclined plane, while $m_B$= 5.0 kg is initially held at a height of h=0.75 m above the floor. (a) What is the maximum value of a coefficient of start friction that would keep the masses from moving? (b) Now assume that the masses will move and $m_B$ is allowed to fall, what will be the resulting acceleration of the masses, if the coefficient of kinetic friction is 0.2? (c) Use your answer to (b) to find the speed of mass B right at the moment when it hits the floor.

4.1. The reason for the different corrosion thicknesses at points A and B in the plot below is: a. The periodic variation in chemistry as the coolant reaches different locations in the fuel rod. b. The decrease in corrosion with decreased coolant temperature after mixing vanes. c. The fact that there are variations in coolant density at different cladding locations. d. The neutron flux varies periodically within the fuel rod and that causes corrosion to change. e. These are mid-pellet and interpellet regions with corresponding variations in heat flux. 4.2. Stress Corrosion cracking can occur if: a. a tensile stress is applied to an existing crack. b. the material has been previously sensitized. c. the environment contains aggressive chemistry. d. all the above conditions are needed for SCC. 4.3. During an x-ray diffraction experiment, taken with Cu Ka radiation (wavelength = 1.5405 Å), coherent scattering from a Zr sample is achieved at 2θ = 36.15°. The corresponding lattice parameter for this plane is approximately: a. 5.22 Å. b. 2.94 Å. c. 1.23 Å. d. 2.46 Å. e. None of the above.
