A. The Heat Flow B. Conductive resistance

plz answer this ASAP,thx   One surface of a copper plate that is 3 cm thick has a constant temperature of 400 ° C while the temperature of the other surface is kept constant at 100 ° C. Describe the temperature profile and how much heat is transferred across the plate ?, k copper = 380 watts/m.k with a cross -sectional area of ​​4 cm².

Consider a wall that is 5 m high, 8 m long, and 0.22 m thick. The thermal conductivities of the various materials used, in W/m °C, are kA = kF = 2, kB = 8, kC = 20, kD = 15 and kE = 35. The left and right surfaces of the wall are maintained at uniform temperatures of 300 °C and 100 °C, respectively. If the heat transfer through the wall is one-dimensional, determine (a) the rate of heat transfer through the wall; b) the temperature at the point where sections B, D, and E meet, and c) the temperature drop across section F. Disregard any contact resistances between the interfaces.
