Answer:
Explanation:
Given:
- cross sectional area of the wire,
- density of aluminium wire,
- young's modulus of the material,
- wave speed,
<u>We have mathematical expression for strain as:</u>
...............................(1)
and since,
where, T = tension force in the wire
equation (1) becomes:
............................(2)
<u>Also velocity ofwave in tensed wire:</u>
...................................(3)
where: linear mass density of the wire
Now, equation (3) becomes
............................(4)
Using eq. (2) & (4) for tension T
putting the respective values
