PLEASE REMEMBER THAT YOU MUST CARRY OUT YOUR CALCULA- TIONS TO AT LEAST THREE SIGNIFI- CANT FIGURES. YOUR ANSWER MUST BE WITHIN ONE PERCENT OF THE CORRECT RESULT TO BE MARKED AS CORRECT BY THE SERVER. 001 (part 1 of 2) 2 points The current I = a t 2- b t + c in a section of a conductor depends on time. What quantity of charge moves across the section of the conductor from t = 0 to t = t 1 ? 1. q = a t 3 1- b 2 t 2 1 + c t 1 2. q = a 3 t 3 1- b 2 t 2 1 + c t 1 correct 3. q = a t 3 1- b t 2 + c t 1 4. q = a 3 t 3 1- b 2 t 2 1 + c 5. q = a t 2 1- b t 1 + c Explanation: The unit of current is Coulomb per second I = d q dt or dq = I dt ....
