Question

A 12 kg hanging sculpture is suspended by a 80-cm-long, 6.0 g steel wire. When the wind blows hard, the wire hums at its fundamental frequency. What is the frequency of the hum

Answer 1

`F=78.3hz`

Step-by-step explanation:

From the question we are told that:

Mass
`m=12`

Length
`l=80cm=0.8m`

Linear density
`\mu= 6.0g`

Generally the equation for Frequency is mathematically given by

`F=(1)/(2l)\sqrt{(T)/(K)}`

`F=(1)/(2(0.8))\sqrt{(12*9.8*0.8)/(6*10^(-3))}`

`F=78.3hz`
