Answer:
When silk is rubbed on a glass rod, an electrostatic charge is generated in a phenomenon known as the triboelectric effect. It is this electric charge that gives you a shock in winter when your rubber-soled shoes rub against a carpeted floor. The triboelectric series is a list of materials sorted according to their electrostatic behavior; using the list, you can predict the electrostatic effects when silk is rubbed on a glass rod.
Explanation:
I am pretty sure that B. How tall the corn grows is the dependent
The student is not a variable in how tall the corn grows, and the question does not indicate any different types of corn in this.
So the independent variable would be the type of fertilizer and the dependent variable would be the height of the corn.
I hope this is right and helps, have a good day!

Answer:
The answer is A. There is no electric field on the interior of the conducting sphere.
Explanation:
A solid conducting sphere in a uniform electric field will exert force on the charges in the sphere to redistribute themselves in such a way that both the charges and the field inside the sphere would vanish.
