If you place a large number of electrons in one small spot on a conductor, they immediately redistribute themselves on the surface because they repel one another. what happens if you place a large number of electron in one small are on the surface of an insulator?
o they immediately redistribute themselves on the surface of the insulator because they repel one another.
o they stay in the area in which they were initially deposited for a relatively long time because they are not free to move about the insulator.
o they immediately redistribute themselves throughout the entire volume of the insulator because they repel one another.

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i.e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i.e. include the distance traveled to the first encounter)
