pls provide full solution for both

PROBLEMS: Show the complete solution. DESCRIBE what you are going to do in each step of the solution you will present. 1. Consider a long, thin, homogeneous copper wire of length L with insulated sides. It is given an initial temperature distribution of f(x)=xC, for 00 if both ends of the rod are kept at 0C and the initial temperature distribution is defined as f(x). 2. If the copper wire has a length L=20cm, diameter of 0.32mm, thermal conductivity at 20C is k= 3.98cmKW, density is =8.96cm3g, and specific heat is Cp=0.385g21, what will be the temperature distribution in the bar?
