How might you measure the amount of energy in the world's largest rice cake?

When you eat the largest rice cake in the world, you increase how many kilograms and multiply by 7,700 will get the energy of the cake.

Explanation: one kilo=7.700 calories

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.
