Unformatted text preview: homework 05 – FAUSAK, TAYLOR – Due: Feb 18 2008, 4:00 am 1 Question 1, chap 27, sect 1. part 1 of 2 10 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 3 t 3 1- b 2 t 2 1 + c 2. q = a 3 t 3 1- b 2 t 2 1 + c t 1 3. q = a t 3 1- b t 2 + c t 1 4. q = a t 2 1- b t 1 + c 5. q = a t 3 1- b 2 t 2 1 + c t 1 Question 2, chap 27, sect 1. part 2 of 2 10 points If I is in A, and a = 4 C / s 3 , b = 3 C / s 2 , and c = 8 C / s, what quantity of charge moves across the section of the conductor from t 1 = 2 s to t 2 = 4 s? Answer in units of C. Question 3, chap 27, sect 3. part 1 of 1 10 points A current of 5 A flows in a copper wire 2 mm in diameter. The density of valence electrons in copper is roughly 9 × 10 28 m- 3 . Find the drift speed of these electrons. Answer in units of m / s. Question 4, chap 27, sect 3. part 1 of 1 10 points A current density of 8 . 2 × 10- 13 A / m 2 exists in the atmosphere where the electric field (due to charged thunderclouds in the vicinity) is 57 V / m....
