Mars’ average temperature is -55o C, while Earth’s is 17oC. Mars’ atmosphere is 95.3% carbon dioxide. Mars’ soil contains no humus and is mostly Sulphur. One day on Mars is approximately 24 hours and 37 minutes. explain whether or not you think life could be supported on Mars. Be sure to use the terms, air, water, soil, and sunlight, in your explanation

listen, you cant how young you were.

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.
