?(a) On a day when the intensity of sunlight is \(1.00 \mathrm{~kW} / \mathrm{m}^{2}\)

Chapter 1, Problem 89

(choose chapter or problem)

(a) On a day when the intensity of sunlight is \(1.00 \mathrm{~kW} / \mathrm{m}^{2}\), a circular lens 0.200m in diameter focuses light onto water in a black beaker. Two polarizing sheets of plastic are placed in front of the lens with their axes at an angle of \(20.0^{\circ}\). Assuming the sunlight is unpolarized and the polarizers are 100% efficient, what is the initial rate of heating of the water in \({ }^{\circ} \mathrm{C} / \mathrm{s}\), assuming it is 80.0% absorbed? The aluminum beaker has a mass of 30.0 grams and contains 250 grams of water (b) Do the polarizing filters get hot? Explain.
