- Newtons Law of Cooling Newtons law of cooling states that the rate of change of temperature of an object is proportional to the difference in temperature between the object and the surrounding medium. Thus, if T is the temperature of the object after t hours and TM is the constant temperature of the surrounding medium, then dTdt=k(TTM) where k is a constant. Use this equation in Exercises 58-61. Show that the solution of this differential equation is T=Cekt+TM where C is a constant.arrow_forwardWaterWater flows into a tank, and a certain part of it drains out through a valve. The volume v in cubic feet of water in the tank at time t satisfies the equation dvdt=5(v/3). If the process continues for a long time, how much water will be in the tank?arrow_forwardFlea Beetles A study of flea beetles found that the change in the rate of flea beetles moving in and out of a patch of beetles could be described by the differential equation dNdt=mN+i where N is the number of beetles in a patch, m is the rate at which beetles move out of the patch, and i is the rate at which they move in. Source: Ecological Monographs. a. Solve the differential equation above with the initial condition N(0)=N0. b. After the researchers cleared a patch of beetles, so that N0, they would return 8 hours later and count the number of beetles. Show that the parameter i can then be estimated by the equation i=mN(8)e8m1 c. The researchers estimated m using the equation m=lnFsd, where Fsd is the fraction of beetles who remained in the patch in which they were released. For the beetles P, striolata released in July in the lush interior of patches 5 meters apart, the average values of Fsd and N(8) were 0.709 and 4.5, respectively. Find the values of m and i.arrow_forward
