 MULTIPLE CHOICE TEST BACKGROUND ORDINARY DIFFERENTIAL EQUATIONS Pick the most appropriate answer.
 Q1. The differential equation                is linear nonlinear linear with fixed constants undeterminable to be linear or nonlinear Q2. A differential equation is considered to be ordinary if it has one dependent variable more than one dependent variable one independent variable more than one independent variable Q3. Given             , y(2) most nearly is 0.17643 0.29872 0.32046 0.58024 Q4. The form of the exact solution to             is   Q5. The following nonlinear differential equation can be solved exactly by separation of variables.                         The value of θ(100) most nearly is -99.99 909.10 1000.32 1111.10 Q6. A spherical solid ball taken out of a furnace at 1200K is allowed to cool in air.  Given the following radius of ball=2 cm density of the ball=7800 kg/m^3 specific heat of the ball=420 J/kg-K emmittance=0.85 Stefan-Boltzman constant=5.67E-8 J/s-m^2-K^4 ambient temperature=300K convection coefficient to air=350 J/s-m^2-K. The differential equation governing the temperature, of the ball as a function of time, t is given by
