- Define Newton’s Law of Cooling. Then name at least three real-world situations where Newton’s Law of Cooling would be applied.arrow_forwardExercise: A tank contains log of salt in 200 liters of water at t = 0. Salt water (18/L) starts to enter into the tank at a rate of 34 min the mixture is drained out of the tank at the same rate. Meanwhile, the mixture Find the quantity of the salt Qct). -350 ( Answer: Q(t) = 200 - 17/30 - 07/0 ). 3arrow_forwardCalculus A 900 L tank contains 450 L of water with a salt concentration of 14 g/L. Water with a salt concentration of 47 g/L flows into the tank at a rate of 82 L/min. The fluid mixes instantaneously, and is pumped out at a specified rate 44 L/min. Let y(t) denote the quantity of salt in the tank at time t. What is the salt concentration when the tank overflows?arrow_forward
- Let y be the percent increase in annual US national production during a year when the unemployment rate changes by u percent. (For example, u=2 if unemployment increases from 4% to 6%.) Okun's law states that y=3.5-2u. (a) What is the meaning of the number 3.5 in Okun's law? (b) What is the effect on national production of a year when unemployment rises from 4% to 8%? (c) What change in the unemployment rate corresponds to a year when production is the same as the year before?Enter the exact answer as a positive value. (d) What is the meaning of the coefficient -2 in Okun's law?arrow_forwardODE Solve the ODEarrow_forwardplease solve using differential calculusarrow_forward

If T=T(t) represents the temperature of a (warm) object at time t, A represents the ambient (cool) temperature, and k is a negative constant of proportionality, which equation(s) accurately characterize Newton's law? A. dTdt=k(A−T) B. dTdt=kT(1−T/A) C. dTdt=kT(T−A) D. dTdt=k(T−A) E. All of the above F. None of the abovearrow_forward
- CALCULUS IIarrow_forwardA tank contains 200 liters of fluid in which 10 grams of salt is dissolved. Brine containing 1 gram of salt per liter is then pumped into the tank at a rate of 5 L/min; the well-mixed solution is pumped out at the same rate. Find the number A(t) of grams of salt in the tank at time t. A(t) = Need Help?
