The ratio of Carbon-12 to Carbon-14 today and in the past is 9: 1. You unearth the remains of a long dead creature and discover how much Carbon-12 and Carbon-14 it currently has. Describe how this ratio, the amount of Carbon-12 today, and the amount of Carbon-14 today are used to determine the absolute age of this creature. Use words, either spoken or written, to convey most of your meaning. You may use additional visuals to make your answer more clear.​

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.
