A cable with a linear density of =0.2 kg/m is hung from telephone poles. The tension in the cable is 500.00 N. The distance between poles is 20 meters. The wind blows across the line, causing the cable resonate. A standing waves pattern is produced that has 4.5 wavelengths between the two poles. The air temperature is T=20C . What are the frequency and wavelength of the hum?
Equation 16.40 states that at distance r away from a point source with power (Power)avg, the wave intensity is I=(Power)avg4r2 Study Figure 16.25 and prove that at distance r straight in front of a point source with power (Power)avg moving with constant speed vS the wave intensity is I=(Power)avg4r2(vvSv)

A sound wave moves down a cylinder as in Active Figure 13.19. Show that the pressure variation of the wave is described by P=smax2s2, where s = s(x, t) is given by Equation 13.25.
Suppose a bat uses sound echoes to locate its insect prey, 3.00 m away. (See Figure 17.6.) (a) Calculate the echo times for temperatures of 5.00°C and 35.0°C. (b) What percent uncertainty does this cause for the bat in locating the insect? (c) Discuss the significance of this uncertainty and whether it could cause difficulties for the bat. (In practice, the bat continues to use sound as it closes in, eliminating most of any difficulties imposed by this and other effects, such as motion of the prey.)
