Witryna30 mar 2024 · Solution. Let T ( t) be the temperature of the object at time t. For convenience, we choose the origin t 0 = 0 of the time scale to be 11:05 so that T 0 = 60. We must determine the time τ when T ( τ) = 72. Substituting T 0 = 60 and T m = − 20 into Equation 4.2.2 yields. T = − 20 + ( 60 − ( − 20)) e − k t. or.
