If Mrs. Unger is familiar with the concept of scaffolding, she is most likely to apply which of the following strategies when her son, Phillip, is having difficulty learning the multiples of 5?a) teach him the multiples of 1 = 5, 2 = 10, and 3 = 5 and then let him try to master the next few multiples before teaching anything further
b) ask Phillip to observe one of his siblings reciting the multiples of 5 and then memorize what he hears
c) have Phillip focus on the multiples he does know so that he doesn't get discouraged
d) provide Phillip with all the multiples of 5 through the number 100 and see how many he can master

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
