An object with initial temperature 150C is placed outside, where the temperature is 35C. Its temperatures at 12:15 and 12:20 are 120C and 90C, respectively. (a) At what time was the object placed outside? (b) When will its temperature be 40C? A ZOOvolt electromotive force is applied to an RCseries circuit in which the resistance is 1000 ohms and the capacitance is 5 X 106 farad. Find the charge q (t) on the capacitor ifi (0) = 0.4. Determine the charge and the current att = 0.0055. Determine the charge as t > 00
