1 point) In a grid of wires, the temperature at exterior mesh points is maintained at constant values as shown in the figure. When the grid is in thermal equilibrium, the temperature at each interior mesh point is the average of the temperatures at the four adjacent points. For instance, T2 T3 20-40 4 T1 = Find the temperatures Ti, T2, T3, T4, when the grid is in thermal equilibrium. T=120 T240 T3 = 60 T4-20 Note: You can earn partial credit on this problenm Preview My Answers Submit Answers You have attempted this problem 3 times. Your overall recorded score is 0%.
