Prelab 10 Questions 1. **If a wire has the dimensions 2 meter long and a radius of 1 mm and the linear density, µ, of 10g/m what is the mass of the wire? (assume completely cylindrical)? 2. Derive a result for the frequency of the string if you know the tension (T), linear density (µ), number of antinodes (n), and the length L? 3. If raising the pitch by one octave in music is when you double the frequency (ie A, 440
