Light passing through a double slit with separation d=3.33*10^-5 creates its first minimum (m=1) at an angle of .551 deg. What is the wavelength of the light in nanometers?
A 10-kg disk-shaped flywheel of radius 9.0 cm rotates with a rotational speed of320 rad/s. Determine the rotational momentum of the flywheel.
Consider two thin, ideal, conducting wires of radius a centered on r? = (?d/2,0,0) and r+ = (d/2, 0, 0), parallel to the z axis and extending to infinity. Assume that both conductors are in a vacuum.
