1. (50 points) In household wiring, usually 12-gauge copper wire (diameter 2.05 mm) is used. A light bulb is connected to power supply through such a wire. A 1.5-Ampere current runs through the wire and the light bulb. a. (10 points) What is the resistance of 10-meter length of the wire? b. (15 points) How many electrons pass through the light bulb each second? c. (10 points) What is the current density in the wire? d. (15 points) If we were to use wire of twice the diameter, which of the above answers would change? Would they increase or decrease? You do not need to do any calculations.

Aparticle's position is given by x = 3.00 - 9.00t + 3t2, in which x is in meters and t is in seconds. (a) what is its velocity at t = 1 s? (b) is it moving in the positive or negative direction of x just then? (c) what is its speed just then? (d) is the speed increasing or decreasing just then? (try answering the next two questions without further calculation.) (e) is there ever an instant when the velocity is zero? if so, give the time t; if not, answer "0". (f) is there a time after t = 3 s when the particle is moving in the negative direction of x? if so, give the time t; if not, answer "0".
