4 ideal linear polarisers are placed in a row with the polarising axis vertical 20° to vertical 55°to vertical and 90°.natural light of intensity I0 incident on the first polarizer. calculate the intensity of light emerging from the last polariser.

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.
