Answer:
The tension in the string is
.
Explanation:
For a string with tension
and linear density
carrying a transverse wave at speed
it is true that

solving for
we get:

Now, the transverse wave covers the distance of 7.4mm in 0.88s, which means it's speed is

And it's linear density (mass per unit length) is

Therefore, the tension in the cord is

or in micro newtons

Ciner forms when there is a series of violent and gentle eruptions resulting in layering of lava and ash
