In the circut drawn below, the switch S is initially open amd the capacitor C is charged with the polarity indicated. the switch is then closed and the capacitor begins discharging through the resistor. which of the following is true of the current that is subsequently induced in the circular wire loop near the long straight wire AB?

A) it is ccw and constant
B) it is ccw and increases with time.
C) it is ccw and decreases with time.
D) it is cw and increases with time.
E) it is cw and decreases with time.

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".
