Problem 2 A metallic ball is initially at 1380K and it's allowed to cool down in air at an ambient /2fiation, the differential STy temperature of 290K. Assuming heat is lost on 138K due to radiath time is: equation that govern the variation of ball temperat dtdT=2.20671012(T481108) Where T is in K and t in seconds. 3. Using Euler's Method, find the variation of temperature with respect to time (Make the plot in MS Excel). 1. Determine the temperature at t=840s
