One of the wavelengths of light emitted by hydrogen atoms under normal laboratory conditions is at ?0 = 656.3nm in the red portion of the electromagnetic spectrum. In the light emitted from a distant galaxy this same spectral line is observed to be Doppler-shifted to ? = 953.3nm , in the infrared portion of the spectrum.
How fast are the emitting atoms moving relative to the earth?
A positive point charge q1=2.5x10^-5C is fixed at the origin of corrdinates and a negative charge Q2=-5x10^-6C is fixed to the x axis at x=+2m
A proton is at the origin and an electron is at the point = 0.45 , = 0.31 . Find the electric force on the proton.
Thermal energy can shift some of the electrons in a hot semiconductor from valence levels to conduction levels. What effect do these shifts have on the semiconductor's ability to conduct electricity.
Kelli weighs 417 N, and she is sitting on a playground swing that hangs 0.44 m above the ground. Her mom pulls the swing back and releases it when the seat is 1.00 m above the ground. Imagine that air resistance is negligible.
