Plane-polarized light is incident on a single polarizing disk with the direction of e0 parallel to the direction of the transmission axis. through what angle should the disk be rotated so that the intensity in the transmitted beam is reduced by a factor of:

An electric current is flowing through the cord below.what will happen to this current if a magnet is brought near the cord? a. the electric current will stop flowing. b. it will exert a force on the voltage. c. the resistance of the wire will decrease. d. it will exert a force on the electric current.

Which of the following correctly describes what happens when an atomic bomb explodes? small pieces of fissionable material are joined and form a body with a mass greater than the critical mass, the relative number of neutrons escaping decreases, and a chain reaction and explosion result. large pieces of fissionable matter are brought together quickly and form a body with a mass smaller than the critical mass, the relative number of escaping neutrons increases, and a chain reaction and explosion result.

If an electric circuit is not grounded it is best to reach out and touch it to provide the ground a.true or b.false
