3 In Fig. 17-26, three long tubes (A, B, and C) are filled with differ- ent gases under different pressures. The ratio of the bulk modulus to the 16B,/Po density is indicated for each gas in terms of a basic value Balpg. 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 simulta- neously.
