OdT dt A coolant is injected into engine fluid, causing the temperature of the engine fluid to decrease with respect to time at a rate that is proportional to the difference of the fluid's instantaneous temperature, T, and the fluid's original temperature, To. Select the differential equation that represents the relationship. (10 points) = c(T-T) T = c(T-T) dt T= t (T-To) T= t (To-T)
