Chapter 16: Q. 28 (page 452)

The density of mercury is 13,600 kg/m3 . What is the speed of sound in mercury at 20°C?

Short Answer

Expert verified

The speed of sound in mercury at20°Cis1448m/s.

Step by step solution

01

Given information

The density of mercury is ρ=13,600kg/m3

TemperatureT=20°C

02

Speed of sound in mercury

Bulk modulus of mercury at 20°Cis B=2.85×1010Pa.

The speed of sound in mercury at the given temperature is

vsound=Bρ=2.85×101013,600≈1448m/s

Therefore, the speed of sound in mercury at20°Cis1448m/s.

A communications truck with a 44-cm-diameter dish receiver on the roof starts out 10 km from its base station. It drives directly away from the base station at 50 km/h for 1.0 h, keeping the receiver pointed at the base station. The base station antenna broadcasts continuously with 2.5 kW of power, radiated uniformly in all directions. How much electromagnetic energy does the truck’s dish receive during that 1.0 h?

FIGURE EX16.9 is the snapshot graph at t = 0 s of a longitudinal wave. Draw the corresponding picture of the particle positions, as was done in Figure 16.9b. Let the equilibrium spacing between the particles be 1.0 cm

FIGURE Q16.8 is a snapshot graph of a sinusoidal wave at t = 1.0 s. What is the phase constant of this wave?

String 1 in FIGURE P16.47 has linear density 2.0 g/m and string 2 has linear density 4.0 g/m. A student sends pulses in both directions by quickly pulling up on the knot, then releasing it. What should the string lengths L1 and L2 be if the pulses are to reach the ends of the strings simultaneously?

The G string on a guitar is a 0.46-mm-diameter steel string

with a linear density of 1.3 g/m. When the string is properly

tuned to 196 Hz, the wave speed on the string is 250 m/s. Tuning

is done by turning the tuning screw, which slowly tightens—and

stretches—the string. By how many mm does a 75-cm-long G

string stretch when it’s first tuned?
