e) To test the engineer's claims, you make measurements using a laser entering into the flat edge of a semicircular prism filled with the engineer's modified water, plotting the results in the linearized graph below. Calculate the actual index of refraction of the modified water n₂. sin(theta_2) 1.00 0.75 0.50 0.25 0.00 0.0 sin(theta_2) 0.901*x + 2.22E-16 0.2 0.4 sin(theta_1) 0.6 0.8

C/ The crystal structure of a particular material consist of a single atom in the center of a cube. The lattice constant is (a), and the diameter of the atom is (ao). Determine the volume density of atoms and the surface density of atoms in the (110) plane.

1:54 O KB/S ul . 52 %3D s the the g With a wooden ruler, you measure the length of a rectangular piece of sheet metal to be 16 mm. With micrometer calipers, you measure the width of the rectangle to be 8.98 mm. Use the correct number of significant figures: What is (a) the area of the rectangle; (b) the ratio of the rectangle's width to its length; (c) the perimeter of the rectangle; (d) the difference between the length and the width; and (e) the ratio of the length to the width?
