Given what you have learned in this extension, which of the following would be the most appropriate assumption to make in a model that uses charged entities to explain static electric effects?

Given what you have learned in this extension, which of the following would be the most appropriate assumption to make in a model that uses charged entities to explain static electric effects?
Select one:
a.
Both negatively (–) and positively (+) charged entities can move through materials and be transferred to other objects.
b.
Positively (+) charged entities can move through materials and be transferred to other objects, but negatively (–) charged entities cannot move.
c.
Negatively (–) charged entities can move through materials and be transferred to other objects, but positively (+) charged entities cannot move.
11- Suppose you had a positively (+) charged object that you wanted to make uncharged. Which would be the easiest way to do so?
Select one:
a.
Add some electrons to it.
b.
Both A and B would be equally easy.
c.
Remove some protons from it.
11- According to the reasoning you applied in the second part of this assignment, when the Styrofoam plate and acrylic sheet have been rubbed together, how does the acrylic sheet acquire a positive charge?
Select one:
a.
Some combination of A, B, C, and D occurs.
b.
Positive (+) charges are created on the acrylic sheet.
c.
The acrylic sheet transfers negative (–) charges to the Styrofoam plate.
d.
Negative (–) charges are destroyed on the acrylic sheet.
e.
The Styrofoam plate transfers positive (+) charges to the acrylic sheet.
12- Taking account of what they learned in this homework assignment a group of students drew these diagrams to represent their revised model for what happens when an acrylic sheet and a Styrofoam plate are rubbed together.
Is there a problem with this model? if so, what is it?
Select one:
a.
The problem is that negatively (–) charged entities have moved.
b.
The problem is that it does not obey the Law of Conservation of Charge.
c.
There are no problems with this model.
d.
The problem is that no positively (+) charged entities have moved.
13- Which of the following is most appropriate to describe what happens when a person discharges a negatively (–) charged object by touching it?
Select one:
a.
Positive charges pass from the object to the person.
b.
Positive charges pass from the person to the object.
c.
Negative charges pass from the person to the object.
d.
Negative charges pass from the object to the person.
14- Which of the following is most appropriate to describe what happens when a person discharges a positively (+) charged object by touching it?
Select one:
a.
Negative charges pass from the person to the object.
b.
Positive charges pass from the person to the object.
c.
Negative charges pass from the object to the person.
d.
Positive charges pass from the object to the person.
