Light from an incandescent source transmits through a polarizer whose transmission axis makes an angle of 37.0° with respect to the vertical; i. e., the 37.0 − ������ ���� on the polarizer lines up with the index mark on the component carrier. The light intensity after passing through the polarizer is 71.3 ���. (a) At what angle would you need to set a second polarizer in order to have no light transmitted through the second polarizer? (b) At what angle would you need to set the second polarizer to obtain a light intensity of 23.4 ���? Assume the polarizers are ideal.

Three charge are arranged as shown in the diagram. the magnitude of the net electrical force acting on the +6 uc charge, rounded to the tenths place, is .

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
