Answer:
The speed of transverse wave will be 28.2842 m/sec
Explanation:
We have given length of the card = 75 cm = 0.75 m
Tension on the card = 320 N
Mass of the card = 120 gram = 0.12 kg
So linear density [tex]=\frac{mass}{length}=\frac{0.12}{0.75}=0.4kg/m[/tex]
We have to find the speed of the transverse wave
Speed is given by [tex]v=\sqrt{\frac{T}{linear\ density}}[/tex]
[tex]v=\sqrt{\frac{320}{0.4}}=28.2842m/sec[/tex]
So the speed of transverse wave will be 28.2842 m/sec
