Chapter 16: Q. 2 (page 451)

The wave speed on a string is 150 m/s when the tension is 75 N. What tension will give a speed of 180 m/s?

Short Answer

Expert verified

The tension of the string is 108 N

Step by step solution

01

Step 1. Write the given information

The speed of the wave is given by v1= 150m/s

The tension of the string is T2=75N

The tension of the string is changed

The new speed of the string is v2= 180m/sec

02

Step 2. To determine the new tension of the string

The formula for the speed of the wave is given by

v=T渭

Here 碌 is the effective mass of the string

As it can be observed that the speed is directly proportional to the square root of tension of the string

v鈭�T

The new tension is given by
v1v2=T1T2
substitute the values,

Therefore, the tension of the string is 108 N

Sound wave A delivers 2 J of energy in 2 s. Sound wave B delivers 10 J of energy in 5 s. Sound wave C delivers 2 mJ of energy in 1 ms. Rank in order, from largest to smallest, the sound powers PA, PB, and PC of these three sound waves. Explain

Oil explorers set off explosives to make loud sounds, then listen for the echoes from underground oil deposits. Geologists suspect that there is oil under 500-m-deep Lake Physics. It鈥檚 known that Lake Physics is carved out of a granite basin. Explorers detect a weak echo 0.94 s after exploding dynamite at the lake surface. If it鈥檚 really oil, how deep will they have to drill into the granite to reach it?

A sound wave with intensity 2.0 * 10-3 W/m2 is perceived to be modestly loud. Your eardrum is 6.0 mm in diameter. How much energy will be transferred to your eardrum while listening to this sound for 1.0 min?

A wire is made by welding together two metals having different densities. FIGURE P16.59 shows a 2.00-m-long section of wire centered on the junction, but the wire extends much farther in both directions. The wire is placed under 2250 N tension, then a 1500 Hz wave with an amplitude of 3.00 mm is sent down the wire. How many wavelengths (complete cycles) of the wave are in this 2.00-m-long section of the wire?
