pls provide full solution for both

1. Consider a iong, thin, homogeneous silver rod of length L with insulated sides. It is given an inical temperature distribution of f(x)=xC, for 00 if both ends of the rod are kept at 0C and the initial temperature diarbuior : defined as f(x). 2. If the silver bar has a length L=10cm, cross-sectional area A=1cm2, thermal conducticy ck= distribution in the bar? FOPSAULAF, fourier sine series Thermal diffusivity Bn=l20lf(x)sinbnxdx c2=Cpk
