Chapter 17: Q3. (page 483)

FIGURE EX17.3a is a snapshot graph at t = 0 s of two waves approaching each other at 1.0 m/s. At what time was the snapshot graph in FIGURE EX17.3b taken?

Short Answer

Expert verified

At t = 3sec

Step by step solution

01

Given Information

In graph a, we are given two waves approaching each other with speed 1m/s.

In graph b we have a snapshot of some future instance of graph a.

02

Comparing both graphs

In graph a initial point of left wave on x axis is at x = 0

In graph b initial point of the wave on x axis is at x = 3.

And the wave is moving towards right with speed of 1m/s.

So this means it must have taken 3 seconds for this initial point to travel from x = 0 to x = 3.

Therefore the snapshot is captured at t=3sec.

A 75 g bungee cord has an equilibrium length of 1.20 m. The

cord is stretched to a length of 1.80 m, then vibrated at 20 Hz. This

produces a standing wave with two antinodes. What is the spring

constant of the bungee cord?

Tendons are, essentially, elastic cords stretched between two fixed ends. As such, they can support standing waves. A woman has a 20-cm-long Achilles tendon鈥攃onnecting the heel to a muscle in the calf鈥攚ith a cross-section area of 90 mm2.. The density of tendon tissue is 1100 kg/m3. For a reasonable tension of 500 N, what will be the fundamental frequency of her Achilles tendon?

The fundamental frequency of an open-open tube is 1500 Hz when the tube is filled with 0掳C helium. What is its frequency when filled with 0掳C air?

Piano tuners tune pianos by listening to the beats between the

harmonics of two different strings. When properly tuned, the note

A should have a frequency of 440 Hz and the note E should be

at 659 Hz.

a. What is the frequency difference between the third harmonic

of the A and the second harmonic of the E?

b. A tuner first tunes the A string very precisely by matching it to

a 440 Hz tuning fork. She then strikes the A and E strings simultaneously

and listens for beats between the harmonics. What

beat frequency indicates that the E string is properly tuned?

c. The tuner starts with the tension in the E string a little low,

then tightens it. What is the frequency of the E string when

she hears four beats per second?
