A 100 kg weight is hanging from the ceiling by a thin copper wire. In its fundamental mode, this wire vibrates at the frequency of 429 Hz. You then increase the temperature of the wire by 29°C. Find the magnitude of the change of fundamental frequency. (Coefficient of linear expansion of copper is 1.7×10⁻⁵ 1/°C.)
A. 0.5 Hz
B. 0.8 Hz
C. 1.0 Hz
D. 1.2 Hz
