A 13 kg hanging sculpture is suspended by a 95-cm-long, 5.0 g steel wire. When the wind blows hard, the wire hums at its fundamental frequency. What is the frequency of the hum

Explanation:

Givens

The frequency is defined by

Where is the speed of the wave in the string and is its wave length.

The wave length is defined as

Now, to find the speed, we need the tension of the wire and its linear mass density

Where and the tension is defined as

Replacing this value, the speed is

Then, we replace the speed and the wave length in the first equation

Therefore, the frequency is

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
