You are attempting to make a simple musical instrument that produces a note with a middle C frequency of 264H z. Your rough plans include a rectangular wooden box with one end closed and the other end open. Strung across the open end of the box is a string with a linear mass density of u = 5.78-2 and a length of 10cm. What should the tension in the string and the length of the wooden box be to create an instrument that when the string is plucked, it creates a standing sound wave in the box whose frequency is 264H z? Note, assume the temperature of the room is 20 C. (20 points)
