Answer:
The tension in the rope is thus 8 N.
Explanation:
Given data:
mass = M = 1.6 kg
length = L = 0.8 m
speed of the wave = v = 2.5 m/s
To find:
Tension on a string =F = ?
Formula:
The speed of a wave on a string is determined by the tension through the formula
v = [tex]\sqrt{F / ( M/L)}[/tex]
Solving for the tension F, we find
F = v^2 M / L
F = (2.5 m/s)^2 x 1.6 kg x 0.8 m
F = 6.25 x 1.6 x 0.8
F = 8 N
