Question

each different material holds on to these surface electrons with its own different characteristic strength. if two materials rub against each other, electrons can be ripped out of the \weaker\ material and find themselves on the material with stronger binding force.
question 6 5 points
what happens to the \weaker material\ when it rubs against something?
select an answer
nothing
it gains electrons from conduction
electrons are ripped away and it loses them
electrons stay neutral

Explanation:

The text states that when two materials rub, electrons are ripped from the "weaker" material (with weaker binding force) and move to the stronger one. So the weaker material loses electrons. Analyzing options: "nothing" is wrong. "Gains electrons" is opposite. "Electrons stay neutral" is irrelevant. The correct option is the one about losing electrons.

Answer:

C. electrons are ripped away and it loses them (assuming the third option is labeled C; if not, the option text: "electrons are ripped away and it loses them")
