2. A spherical nuclear fuel pellet of radius 1cm produces heat as a result of radioactive decay. The pellet is covered by a spherical jacket with a thickness of 1cm and a thermal conductivity of 0.07W/m.K. At steady-state, the temperature on the surface of the jacket is 50C and the temperature on the surface of the pellet is 95C. (a) Determine an expression for temperature as a function of radial position and using MATLAB or Excel, plot this temperature profile. (b) Determine the heat flux at the surface of the pellet
