1. Consider a speaker at some fixed position, emitting sound uniformly in all directions. You are standing at some distance d from this speaker, holding a sound-intensity measuring device. You then walk 25.0 m in a straight line towards the speaker. At this point you observe that the intensity of the sound has doubled (from the previous location). Determine the distance d. There are no echoes or reflections or interference. 2. You are standing equidistant from four identical jet engines...
