C
Explanation:

<span>CorrectThe direction of the electric field stays the same regardless of the sign of the charges that are free to move in theconductor.Mathematically, you can see that this must be true since the expression you derived for the electric field isindependent of .Physically, this is because the force due to the magnetic field changes sign as well and causes positive charges tomove in the direction (as opposed to pushing negative charges in the direction). Therefore the result isalways the same: positive charges on the side and negative charges on the side. Because the electric fieldgoes from positive to negative charges will always point in the direction (given the original directions of</span>
Answer:
convenience sample
Explanation:
Convenience sampling is most important and is useful in pilot testing of a product.
It is a type of sampling, that is a non probability sampling in which a sample is taken for testing which is a part of a group of sample products which is close to hand. It is usually taken from the part which is easily accessible or easy to reach.
In the question, Gerrard asks his survey team to interview the customers who are readily accessible at their outlets. This gives an example of convenience sampling.
