Question 3: (3 Points) Consider A 2m rod that has a thermal conductivity of = 1/10. The rod is cooled on both ends (to ensure that the temperature at the ends is always 0). The middle of the rod is heated for a period after which the temperature on the rod is H(z) = 300z 15022 The heating is then immediately removed from the rod, and the rod is left to cool. (You may assume that this happens when = (). After how many (whole) seconds is the first time the temperature over the entire rod uniformly equal to 0 within +0.0057 Note: You will, of course, need to solve the Heal Equation to answer the question. In order to find the precise second to answer the question, you may use Desmos or other software to, but must nonetheless explain and Justify your answer in the submission
