To practice problem-solving strategy 30.1: inductors in circuits. a circuit has a 1 v battery connected in series with a switch. when the switch is closed, the battery powers two paths in parallel, one of which has a resistor of resistance r1 = 95 ω in series with an inductor of inductance l = 1.5×10−2 h , while the other has a resistor of resistance r2 = 360 ω . what is the current supplied by the battery at a time t = 0.4 ms after the switch is closed?

Why is the energy that results from a roller coaster's position at the top of a hill referred to as potential energy?

To understand the behavior of the electric field at the surface of a conductor, and its relationship to surface charge on the conductor. a conductor is placed in an external electrostatic field. the external field is uniform before the conductor is placed within it. the conductor is completely isolated from any source of current or charge. part a: which of the following describes the electric field inside this conductor? it is in the same direction as the original external field.it is in the opposite direction from that of the original external field.it has a direction determined entirely by the charge on its surface.it is always zero. part b: the charge density inside the conductor is: 0non-zero; but uniformnon-zero; non-uniforminfinite part c: assume that at some point just outside the surface of the conductor, the electric field has magnitude e and is directed toward the surface of the conductor. what is the charge density η on the surface of the conductor at that point? express your answer in terms of e and ϵ0
