Answer :
Final answer:
The speed of sound in the copper wire, with sound travelling at intervals of 0.315 ms and the wire being 1.5 meters long, is calculated to be approximately 4761.90 m/s.
Explanation:
To calculate the speed of sound through copper wire when sound moves through it at intervals of 0.315 ms, we need to use the formula speed = distance/time. Given that the wire is 1.5 meters long and it takes sound 0.315 milliseconds to travel through it, we first convert time into seconds by dividing 0.315 milliseconds by 1000, which gives us 0.315 × 10-3 seconds. The speed of sound in the copper wire is therefore 1.5 meters divided by 0.315 × 10-3 seconds, which results in approximately 4761.90 m/s.
