b) use the explicit method tosolve for the temperature distribution att=O.5sofalong thin rod with a length Of 8 Crn and the following values: k' = 0.490 call(S cm K), Ax = 2.00 and At = 0.100 s. At t = O. the temperature of the rod is 115 K and the boundary conditions are fixed for all times at T(O Crn) = 400 K and = 350 K. Note that the rod is aluminum with C = 0.2114 cal/(g K) and p = 3 2.7 g/cm
