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 is pulled taut with a tension of 8.6 N, how much time does it take for a wave to travel from one end of the string to the other ?

Respuesta :

Answer:

Wave will take 0.00372 sec to travel from one end to other end

Explanation:

We have given mass of the string m = 32 gram = 0.032 kg

Length of the string l = 9.5 m

Tension F = 8.6 N

We know that speed of the wave is given by

[tex]v=\sqrt{\frac{Tl}{m}}=\sqrt{\frac{8.6\times 9.5}{0.032}}=2553.125m/sec[/tex]

Now time [tex]t=\frac{length }{speed}=\frac{9.5}{2553.125}=0.00372sec[/tex]

Wave will take 0.00372 sec to travel from one end to other end
