The figure shows wire section 1 of diameter D;- 5.0OR and wire section 2 of diameter D2- 3.00R, connected by a tapered section. The wire is copper and carries a current. Assume that the current is uniformly distributed across any cross-sectional area through the wire's width. The electric potential change V along the length L-2.10 m shown in section 2 is 11.0 pV. The number of charge carriers per unit volume is 8.80 x 10 m. What is the drift speed of the conduction electrons in section 1? D (1) Number Units
