Unpolarized light of intensity I0 passed through an ideal polarizing sheet with its plarizing axis at the 12 o'clock position and then through a second ideal sheet with its polarizing axis at the 1 o'clock position. What is the intensity of the emerging light in terms of I0? A) (3/8)IO.
B) (1/8)IO.
C) (3/7)IO.
D) (3/10)IO.
E) (2/5)IO.

The field lines around one end of a bar magnet are shown below based on the diagram, what can you conclude about the pole of the magnet? a.is a south pole because the field hnes spread out from this end b.a north pole because the field lines spread out from this end c.a nouth pole because the field lines enter the magnet at this end d.is a north pole because the field lines enter the magnet at this end
