**Classical Mechanics**Level 3

*Details and Assumptions*

The distance between A and B is 25 cm

Temperature of the rainy day: 290 K

Temperature of the sunny day: 300 K

Assume the resonance frequency varies with the temperature due to dilatation and follows this function: \( f(T)=\left[ \frac { 1 }{ 9 } \times \frac { T }{ \left\{ K \right\} } -\frac { 260 }{ 9 } \right] \left\{ Hz \right\} \)

f is the resonance frequency. The K and Hz in braces are just for the dimension to be correct.

This problem was inspired in something my teacher said and in this site: Resonance and Damping
