Answer:
The time taken is
Explanation:
From the question we are told that
The length of steel the wire is
The length of the copper wire is
The diameter of the wire is
The tension is
The time taken by the transverse wave to travel the length of the two wire is mathematically represented as
Where is the time taken to transverse the steel wire which is mathematically represented as
here is the density of steel with a value
So
And
