You hear a sound with a frequency of 256 hz. the amplitude of the sound increases and decreases periodically: it takes 2 seconds for the sound to go from loud to soft and back to loud. this sound can be thought of as a sum of two waves with frequencies:

(a) 256 hz and 2 hz.
(b) 254 hz and 258 hz.
(c) 255 hz and 257 hz.
(d) 255.5 hz and 256.5 hz.
(e) 255.75 hz and 256.25 hz.

Suppose that two tanks, 1 and 2, each with a large opening at the top, contain different liquids. a small hole is made in the side of each tank at the same depth 1.57 m below the liquid surface, but the hole in tank 2 has 2.49 times the cross-sectional area of the hole in tank 1. (a) what is the ratio ρ1/ρ2 of the densities of the liquids if the mass flow rate is the same for the two holes? (b) what is the ratio rv1/rv2 of the volume flow rates from the two tanks? (c) at one instant, the liquid in tank 1 is 14.9 cm above the hole. if the tanks are to have equal volume flow rates, what height above the hole must the liquid in tank 2 be just then?
