Problem: Light from a hydrogen discharge lamp with a wavelength of 656.45 nm is used in a Michelson interferometer. The second mirror is moved 9.00000 cm.
Part A: How many fringe shifts are observed?
I need help to determine how many fringe shifts are observed.
A bullet of mass 6.3 g is fired horizontally into a 1.2 kg woodenblock at rest on a horizontal surface. The coefficient of kineticfriction between block and surface is 0.25.
Singly ionized helium He+ is hydrogenlike. (a) Construct a carefully scaled energy level diagram for He+, showing the levels for n=1, 2,3,4,5, and 8. (b) What is the ionization energy of He+?
suppose that r2/r1 = 10.0 cm and ignoring any air inside the shell, find the temperature of the outer surface of the shell.
A physics professor is pushed up a ramp inclined upward at an angle 35.0^\circ above the horizontal as he sits in his desk chair that slides on frictionless rollers. The combined mass of the professor and chair is 84.0kg . He is pushed a distance ..
A small sphere (emissivity = .9, radius = r1) is located at the center of a spherical asbestos shell (thickness = 1cm, outer radius = r2). The thickness of the shell is small compared to the inner and outer radii of the shell.
