Chapter 16: Q. 6 (page 451)

Draw the snapshot graph D(x, t = 0 s) at t = 0 s for the wave shown in FIGURE EX16.6.

Short Answer

Expert verified

The snapshot graph of the wave has been shown

Step by step solution

01

Write the given information 

The history graph of the wave is given at distance x=2m
The velocity of the wave is given as v= 1 m/.sec
The wave is traveling to the right.

02

To draw the snapshot graph of the wave at time t= 0 sec 

A snapshot graph shows the displacement of the wave with respect to the position at a given time whereas a history graph shows the displacement of the wave with respect to the time at a given position.


Analyze the history graph

  • With every second, the wave travels 1-meter to the right
  • In 4 seconds, the wave would travel 4-meters


The snapshot graph is shown below.

One way to monitor global warming is to measure the average

temperature of the ocean. Researchers are doing this by measuring the time it takes sound pulses to travel underwater over large distances. At a depth of 1000 m, where ocean temperatures hold steady near 4C, the average sound speed is 1480 m/s. It’s known from laboratory measurements that the sound speed increases 4.0 m/s for every 1.0C increase in temperature. In one experiment, where sounds generated near California are detected in the South Pacific, the sound waves travel 8000 km. If the smallest time change that can be reliably detected is 1.0 s, what is the smallest change in average temperature that can be measured?

Earthquakes are essentially sound waves—called seismic

waves—traveling through the earth. Because the earth is solid, it can support both longitudinal and transverse seismic waves. The speed of longitudinal waves, called P waves, is 8000 m/s. Transverse waves, called S waves, travel at a slower 4500 m/s. A seismograph records the two waves from a distant earthquake. If the S wave arrives 2.0 min after the P wave, how far away was the earthquake? You can assume that the waves travel in straight lines, although actual seismic waves follow more complex routes.

A 20.0-cm-long, 10.0-cm-diameter cylinder with a piston at

one end contains 1.34 kg of an unknown liquid. Using the piston

to compress the length of the liquid by 1.00 mm increases the

pressure by 41.0 atm. What is the speed of sound in the liquid?
