Q1. Two speakers, one directly behind the other, are each generating a 374-Hz sound wave. What is the smallest parting distance between the speakers that will generate destructive interference at a listener standing in front of them? Take the speed of sound to be 374 m/s.
Q2. Old English children's rhyme states, "Little Miss Muffet sat on a tuffet, eating her curds and whey, while along came the spider who sat down beside her..." The spider sat down not because of the curds and whey but because Miss Muffet had a stash of 32 tuffets of dried flies. The volume measure of a tuffet is given by 1 tuffet = 2 pecks = 0.50 Imperial bushel, where 1 Imperial bushel = 36.3687 liters (L). What was Miss Muffet's stash in the units?
