Suppose the student's data show that the tomato plants that received the least sunlight produced the heaviest tomatoes. However, the plants that received the most sunlight produced tomatoes with the largest volume. What would be the best thing for the student to do next?

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
