Q1. Compute the distance of two point's p1 and p2 in the x-y plane with the following Cartesian coordinates: p1= (-5m, +8m), p2= (+3m, +2m). Draw the position vectors into appropriate-points.

Q2. Unpolarized light with an average intensity of 845 W/m2 enters a polarizer with a vertical transmission axis. The transmitted light after that enters a second polarizer. The light that exits the second polarizer is found to have an average intensity of 224 W/m2. What is the orientation angle of the second polarizer relative to the first one?
