**1.**

The wave velocity can also be expressed as:

$\overline{){\mathbf{v}}{\mathbf{=}}\sqrt{\frac{\mathbf{T}}{\mathit{\mu}}}}$

**1.** Derive a formula for linear mass density μ in terms of the wave speed v and string tension T.

Assume you have the following intermediate (i.e., significant figures may be incorrectly stated) experimental results :

L = | 0.812 ? 0.019 m |

f_{1} = | 29.02 ? 1.45 Hz |

T = | 5.08 N (exact) |

**2.** What is the linear mass density of the string (without uncertainty, units requred)?
