this one is stumping me:
The intensity level of 15 car engines in a garage is 100 dB.What is the intensit levelgnereated by ONE engine?
i thought to just take 100 and divide by 15 but there sounded too easy.
edit: here it is: A person stands in front of two stereo speakers driven by the same oscillator providing a 200 Hz tone. the speed of sound in the room is 330 m/s. The person is standing 1.65 meters from one speaker and 4.95 meters form the other. is the person standing on anode or an antinode?
