A popular car stereo has four speakers, each rated at 60 W. In answering the following questions, assume that the speakers produce sound at their maximum power. Part A Find the intensity I of the sound waves produced by one 60-W speaker at a distance of 1.0 m. Express your answer numerically in watts per square meter. Use two significant figures. Part B Find the intensity I of the sound waves produced by one 60-W speaker at a distance of 1.5 m. Express your answer numerically in watts per square meter. Use two significant figures. Part C Find the intensity I of the sound waves produced by four 60-W speakers as heard by the driver. Assume that the driver is located 1.0 m from each of the two front speakers and 1.5 m from each of the two rear speakers. Express your answer numerically in watts per meter squared.
