Find an expression for the heat transferred through a rectangular slab

1.	Find an expression for the heat transferred through a rectangular slab of area of cross-section A, thickness d in time t. Its two faces are maintained at temperatures Th and Tc (Th > Tc ) respectively. An electron and photon each have a wavelength 1.00 find the energy of photon and electron.
Answer» ss = dArea of cross section = Atime = tLet the conductivity = kThe TWO faces are at temperatures Th and Tc(Th>Tc).So the HEAT flow rate is GIVEN asHeat TRANSFERRED =Q
