Can you please answer this physics question?

A 45cm guitar like string is plucked and is resonating with a frequency of 512Hz. The string appears to have 3 nodes, (including the ends). 1. If the string has 10N of force applied to it, what is the linear density of the string? 2. how fast is the sound traveling through the wire? Thank you for any responses!! :) show more A 45cm guitar like string is plucked and is resonating with a frequency of 512Hz. The string appears to have 3 nodes, (including the ends).
