In one test, between two concentric cylinders (20 cm long, 1 and 2 cm radius), with very thin walls, glycerin is placed; keeping the outer cylinder fixed, the other is rotated by applying a moment of 26 kdina.cm to it. Under such conditions, the velocity in the glycerin (V, in m / s) changes with the distance to the axis (r, in m), according to the equation V = 0.4 / r - 1000 * r At what temperature was...

Monochromatic light of wavelength λ1 is sent through two closely-spaced slits separated by a distance d1 = 1.8 mm. A resulting interference pattern is shown on a screen L1 away. Another monochromatic light source, this one of wavelength λ2, is sent through a diffraction grating toward the same screen, resulting in a second interference pattern. The diffraction grating is a distance L2 from the screen and has 400 lines per mm etched onto it. A) Assume that L1 = L2...
