Question

which statement should she place in the region marked x? electrons move between objects. the objects do not touch. the objects develop opposite charges. the objects have the same charge.

Explanation:

1. Analyze each option:

• Option 1: In both friction (when objects rub, electrons transfer) and conduction (direct contact, electrons move), electrons move between objects. This is a commonality.
• Option 2: In conduction, objects touch, so this is not a commonality.
• Option 3: In friction, objects develop opposite charges; in conduction, the charging object and the conductor end up with the same type of charge (e.g., both negative if the charging object is negative and electrons move to the conductor), so this is not a commonality.
• Option 4: As explained for option 3, they don't always have the same charge.

Answer:

Electrons move between objects.
