A guitar string is 0.620 m long, and oscillates at 234 Hz. What is the
velocity of the waves in the string?
(Unit = m/s)
please help will give brainliest

Explanation:

We have,

Length of a guitar string is 0.62 m

Frequency of a guitar string is 234 Hz

For guitar string,

\begin{gathered}L=2\lambdalambda=\dfrac{L}{2}lambda=\dfrac{0.62}{2}lambda=0.31\ m\end{gathered}

L=2λ

λ=

2

L

λ=

2

0.62

λ=0.31 m

The velocity of the wave in the string is given by :

\begin{gathered}v=f\lambdav=234\times 0.31v=72.54\ m/s\end{gathered}

v=fλ

v=234×0.31

v=72.54 m/s

So, the velocity of the waves in the string is 72.54 m/s

580.32 m/s

Explanation:

a guitar string can only make a phase of 1/4 wave, so

0.620 = ¼ wavelenght

wavelenght = 4 * 0.620 m = 2.48 m

v = wavelenght * frequency

v = 2.48 * 234 = 580.32 m/s

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary

probably not if net force is zero
