1. A 55kg Olympic diver can jump .65 m high on solid ground. With the help of bouncing on the diving board, she can jump 2.5 m above the board. How much elastic energy is stored in the diving board? (Hint: make the initial situation when the diving board is bent down the most and the final situation when the diver is at her highest point.)

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of ΞΈ_1=20.8β with the incident electric field. polarizer b has its axis at an angle of ΞΈ_2=63.0β with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?
