A brother and sister try to communicate with a string tied between two tin cans. If the string is 9.5 m long, has a mass of 32 g, and pulled taut with a tension of 8.6 N, how long does it take a wave to travel from one end of the string to the other?
The speed of a wave in a wire depends on the wire's linear density and the tension given.
Wave speed V = sqrt [F/D], ...
Solution gives all mathematical steps.
