Maglev trains, like the one shown in the picture, to 600 miles per hour. Magnets on the
use magnet fields to travel up
bottom of the train and on the tops of the rails have
similar magnetic poles. Based on
properties of magnets, how do
ose magnets affect the train?

An ideal polarizer with its transmission axis rotated 30 degrees to the vertical is placed in a beam of unpolarized light of intensity 10w/m^2. after passing through the polarizer, what is the intensity of the beam? a. 8.7 w/m^2 b. 7.5 w/m^2 c. 5.0 w/m^2 d. 10 w/m^2 e. 2.5 w/m^2
