The following are positioned in sequence: a source of beam of natural light intensity i0; three ideal polarizers a, b, c; and an observer. polarizer axis angles are measured clockwise from the vertical, from the perspective of the observer. the axis of polarizer a is set a zero degrees (vertical), and the axis angle of polarizer c is set at 50 degrees. a) if polarizer b is set so the beam intesity is zero at the observer, what are the two possible axis angle settings of polarizer b? b) if polarizer b is set so that the beam intensity at the observer is a maximum, what is the axis angle of the polarizer b? show detailed stepsc) if the axis angle of polarizer b is set to 120degrees, what is the ratio of the intensity of the beam at the observer to the intensity of the source?

Aheavy boy and a lightweight girl are balanced on a massless seesaw. the boy moves backward, increasing his distance from the pivot point. what happens to the seesaw? it is impossible to predict without knowing additional information. the side the boy is sitting on will tilt downward. the side the girl is sitting on will tilt downward. nothing; the seesaw will remain balanced.
