sites in and around Chicago? (1 point)
d. Explain why you would expect to find silver carp DNA at Chicago site 2 if you find silver carp DNA at Chicago site 1 and North Shore sites 1 and 2. (1 point)

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
