Question 1)- A rod with rectangular cross-sectional area as shown below is exposed to convection on its top and bottom surfaces, while receiving constant surface heat flux from bottom surface. At the steady state condition, the rod is producing volumetric energy $q_g \frac{W}{m^3}$ while its two ends are kept at constant surface temperature $T_1$. a) Using slicing method (Method of extended surfaces) find the temperature profile inside the rod. b) Locate the location and value of maximum temperature in the rod. Note: $T = T(x)$. $T_{\infty} = 25 \text{ [°C]}, h = 50 \frac{W}{K \cdot m^2}, q''_s = 100 \frac{W}{m^2}, \dot{q}_g = 5 \times 10^5 \frac{W}{m^3}, T_1 = 20 \text{ [°C]}$ $k = 400 \frac{W}{m \cdot K}, W = 8[mm], h = 3[mm], L = 100[mm]$

Bonds rated B have a 35% chance of default in five years. Bonds rated CCC have a 65% chance of default in five years. A portfolio consists of 40% B-rated and 60% CCC-rated bonds. If a randomly selected bond defaults in a five-year period, what is the probability that it was a B-rated bond? (Enter your answer as a percent rounded to one decimal place. For example, a 65% chance would be entered as 65.0 and not 0.650 or 0.7).
