Answer:
The tension in the string is 78.73 N.
Explanation:
The tension in the string can be determined from the expression;
v =
where: v is the speed of the wave in the sting, T is the tension in the string and m is the mass per unit length of the sting.
Given that: v = 16.2 m/s, and m = 0.3 kg/m.
Then;
16.2 =
Square both sides to have,
=
T = x 0.3
= 252.44 x 0.3
= 78.732
T = 78.732 N
The tension in the string is 78.73 N.
