The work done by the machine is equal to the product between the force applied and the distance over which the force is applieds, so in this case:
And the power of the machine is equal to the ratio between the work done by the machine and the time taken:
And the power of the machine is equal to the ratio between the work done by the machine and the time taken:
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
is the time taken to transverse the copper wire which is mathematically represented as
