Question
a) Determine the temperature of the body at any time by solving equation (2). u(t) b) Use a graphing utility to plot the graph of u versus t. c) Find the time 7 at which u(7) = 500 —that is, twice the ambient temperature. Up to this time the error in using equation (2) to approximate the solutions of equation (1) is no more than 1%. T = K S

Heat transfer from a body to its surroundings by radiation, based on the Stefan-Boltzmann law, is described by the differential equation du -a(u² – T¹4¹) (1) dt where u(t) is the absolute temperature of the body at time t, T is the absolute temperature of the surroundings, and a is a constant depending on the physical parameters of the body. However, if u is much larger than T, then solutions of equation (1) are well approximated by solutions of the simpler equation = du —auª. (2) dt Suppose that a body with initial temperature 2100 K is surrounded by =
