Consider $1-$D$,$ transient, constant properties problem.

$2L=0\mathrm{.}1m$

$k_{\text{w}\text{a}\text{l}\text{l}}=10\frac{W}{mC},c_p=500\frac{j}{kgC},=1000k\frac{g}{m^2}$

$T_i=100C,T_{}=20C,h=60\frac{W}{m^{2}C}$

Could you please solve each premise step by step? It is very important for me to be transaction oriented rather than answer oriented. Thanks in advance.

d$)$ Obtain the temperatures at the following points using the analytical solution in the text book $($Do not use one$-$term solution unless applicable: $<mn\; id="EditorElement\_11901981">0</mn><mn\; id="EditorElement\_11901982">.</mn><mn\; id="EditorElement\_11901983">2</mn>$ :

$))=0,t=(15))=0\mathrm{.}025,t=(15))=0\mathrm{.}05,t=(15))=0,t=(30))=0\mathrm{.}025,t=(30))=0\mathrm{.}05,t=(30))=0,t=(45))=0\mathrm{.}025,t=(45))=0\mathrm{.}05,t=(45$

For each time $(15,30,45),$ connect the $3$ points with a spline and add them to the previous figure.
