A wire of mass 10 grams and length 30 cm has both ends fixed and is vibrating at its fundamental frequency of 20 Hz.
What is the tension of the string?
What is the speed of the wave on this string?

A sting gets a lot of a tension from me. Apply the same to your homework.

You can do the math yourself but here are the formulas.
velocity = frequency * wavelength
velocity = SQRT (Tension /( Mass / Length))
You know have two equations and two unknowns you can solve for one and plug into the other and solve completely.
By the way, hyperphysics normally has all the formulas you need for freshmen physics.
