Question 8 (10 points) The terminals of a 0.70 V watch battery are connected by a 100 m long gold wire with a diameter of 0.10 mm. What is the current in the wire? Resistivity of the gold is 2.4 x 10-8 ohm-m. 86.4 mA 14.7 mA 38.5 mA 2.3 mA
Question 9 (10 points) Two 5 mm x 5 mm electrodes are held 0.10 mm apart and are attached to a 9 V battery. Without disconnecting the battery, a 0.1 mm thick sheet of Mylar is inserted between the electrodes. What are the capacitor's charge before and after the Mylar is inserted. Dielectric constant of Mylar is 3.1 O capacitor's charge is equal before and after the Mylar is inserted before 95 PC (pico-Coulomb) and after 205 pC. before 20 pC (pico-Coulomb) and after 62 pC. Obefore 148 PC (pico-Coulomb) and after 315 pC. Obefore 418 PC (pico-coulomb) and after 607 PC.
