1. for part 1 of your datasheet, wire up the circuit in fig. 4.3. section 4.2.1. set r to low value (~50ohms) for section 4.2.1 only. what is the resonant frequency of your lc circuit? (1 point) 2. what is the percent difference from the theoretical value of f0 and the observed value you found in question 1? (for l, use the value displayed on your inductor) note: theoretically, f (1 points) 0 = 1 (2π√lc) 3. knowing c and using your observed f0 , calculate l. show your work, and include units throughout. how close is this to the value of l displayed on your inductor? (2 point)

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

Complete these sentences. if a roller coaster train has a potential energy of 1,500 j and a kinetic energy of 500 j as it starts to travel downhill, its total energy isj. once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 j, and its potential energy decreases to j. when the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isj.
