In Figure 33-48a, a light ray in a liquid (n = 1.61) is incident at angle 1 on a boundary with an underlying material, into which some of the light refracts. There are two choices of underlying material. For each, the angle of refraction 2 versus the incident angle 1 is given in Figure 33-48b...
An electron is placed in a magnetic field B that is directed along a z axis. The energy difference between parallel and antiparallel alignments of the z component of the electron's spin magnetic moment with B is 4.50 10-25 J. What is the magnitude of B?
energy=Beh/4pim 4.5e-25 = B...
A metal strip 7.50 cm long, 0.550 cm wide, and 0.800 mm thick moves with constant velocity v through a magnetic field B = 1.00 mT pointing perpendicular to the strip, as shown in Figure 28-35. A potential difference of 3.90 µV is measured between points x and y across the strip. Calculate the...
Figure 26-24a gives the magnitude E(x) of the electric fields that have been set up by a battery along a resistive rod of length 9.00 mm . The rod consists of three sections of the same material and length but with different radii. The radius of section 3 is 5.00 mm.
E for section 1 is...
