In Fig. 17-26, three long tubes(A, B, and C) are filled with different gases under different pressures. The ratio of the bulk modulus to the density is indicated for each gas in terms of a basic value . Each tube has a piston at its left end that can send a sound pulse through the tube (as in Fig. 16-2).The three pulses are sent simultaneously. Rank the tubes according to the time of arrival of the pulses at the open right ends of the tubes, earliest first.
A sound source sends a sinusoidal sound wave of angular frequency and amplitude through a tube of air. The internal radius of the tube is .
(a) What is the average rate at which energy (the sum of the kinetic and potential energies) is transported to the opposite end of the tube?
(b) If, simultaneously, an identical wave travels along an adjacent, identical tube, what is the total average rate at which energy is transported to the opposite ends of the two tubes by the waves? If, instead, those two waves are sent along the same tube simultaneously, what is the total average rate at which they transport energy when their phase difference is

(d) ,
(e)?
Question: When the door of the Chapel of the mausoleum in Hamilton, Scotland, is slammed shut, the last echo heard by someone standing just inside the door reportedly comes 15 slater. a) If that echo were due to a single reflection off a wall opposite the door, how far from the door is the wall? (b) If, instead, the wall is 25.5 maway, how many reflection (back and forth) correspond to the last echo?
You can estimate your distance from a lightning strike by counting the seconds between the flash you see and the thunder you later hear. By what integer should you divide the number of seconds to get the distance in kilometers?
Question: A column of soldiers, marching at 120paces per minute, keep in step with the beat of drummer at the head of the column. The soldiers in the rear end of the column are striding forward with the left foot when the drummer is advancing with the right foot. What is the approximate length of the column?
