Answer:
Stringed instruments (chordophones).
Explanation:
Musical instruments that produce sound by vibration of a stretched string are called stringed instruments (chordophones).
Some examples of stringed instruments are guitar, piano, harp, violin, sitar etc.
A guitar can be defined as a musical instrument with six or twelve strings and a long fretted fingerboard that are being played using a plectrum or by strumming (plucking) with the fingers, usually in a downward direction.
Basically, a guitar is a musical instrument that produces sound through regular vibrations and as a result of this, it is used for creating uniform and melodious sounds.
We are given the following values:
weight w = 240 lb = 1,067.52 N
energy E = 3,000 J
The formula for potential energy is:
E = w h
where h is the height the person has to climb, therefore:
h = 3000 / 1067.52
<span>h = 2.81 m</span>
<span>
</span>
<span>Therefore he has to climb 2.81 meters</span>
