A stationary storm system in the mid-Atlantic creates long ocean waves whose wavelength is 64.4 m. It takes the waves 3.90 days to travel from the storm to Miami, Florida (U.S.). These waves pass under a bird that is floating in the ocean. Starting from a trough, 3.21 s pass before the bird is next on a crest. How far is the storm from Miami?
You are standing 3.08 m from a loudspeaker and you detect an intensity level of 93.7 dB. At what distance from the loudspeaker would the intensity level be a more comfortable 77.6 dB? Assume the loudspeaker is an isotropic source.
