As you are sliding down a plastic slide in a playground, your hair stands up on its ends. Which statement best explains why your hair stands up after sliding down the plastic slide?

Question

options:

Energy is transferred from you to the slide through conduction, causing your hair to become charged and stand up.
Energy is transferred from you to the slide through conduction, causing your hair to become charged and stand up.

Friction causes a transfer of electrons between the slide and you, making each of your like-charged hairs repel each other.
Friction causes a transfer of electrons between the slide and you, making each of your like-charged hairs repel each other.

Energy is transferred from the slide to you through induction, causing your hair to become charged and stand up.
Energy is transferred from the slide to you through induction, causing your hair to become charged and stand up.

Friction causes a transfer of electrons between the slide and you, making your like-charged hairs attract the air through induction.

Answer 1

The statement that best explains why your hair stands up after sliding down the plastic slide is:

Friction causes a transfer of electrons between the slide and you, making each of your like-charged hairs repel each other.

When you slide down the plastic slide, friction causes electrons to transfer between the slide and your body. This process can result in your body becoming negatively charged (or positively charged depending on the materials in contact), leading to like charges on your hair. Since like charges repel, your hair stands up as it tries to get as far away from each other as possible.

Answer 2

Which statement about electric insulators is true?

Electric insulators are the best heat conductors.
Electric insulators are the best heat conductors.

Charges within electric insulators do not readily move.
Charges within electric insulators do not readily move.

Electric charges move freely in electric insulators.
Electric charges move freely in electric insulators.

Electric insulators have a high flow of heat and electricity.

Answer 3

The true statement about electric insulators is:

Charges within electric insulators do not readily move.

Electric insulators are materials that do not allow electricity to flow freely through them. This is because the charges (such as electrons) within the insulators are not able to move easily. Examples of insulators include rubber, glass, and plastic.
