The energy was transferred from the slide to the child through induction, causing the child's hair to become charged and stand up.
Friction caused a transfer of electrons between the slide and the child, making each of his like-charged hairs repel each other.

how do you know?
I know this because when the child slides down the plastic slide, it generates a static charge due to friction. This static charge causes a transfer of electrons between the child and the slide, making each of his like-charged hairs repel each other. Therefore, the child's hair stands up after he slides down the slide.
oh okay, Thanks!
You're welcome! If you have any more questions, feel free to ask.
The correct answer is:
Friction caused a transfer of electrons between the slide and the child, making his like-charged hairs attract the air through induction.
To understand why the child's hair stands up after sliding down the slide, we need to consider the concept of static electricity. Static electricity occurs when there is a build-up of electric charge on the surfaces of objects. Friction plays a role in creating static electricity by causing the transfer of electrons between two objects.
In this case, as the child slides down the plastic slide, there is friction between the child's hair and the slide's surface. This friction causes the transfer of electrons from the child's hair to the slide, creating a build-up of electric charge. Consequently, the child's hair becomes positively charged.
With the child's hair now positively charged, it repels each other due to like charges. This repulsion causes the strands of hair to stand up, as they try to move away from each other.
Additionally, the child's positively charged hair can also attract neutral objects or substances in its vicinity through a phenomenon called induction. As the positively charged hair repels each other, it creates an electric field around it. This electric field induces a separation of charges in nearby neutral objects, making them temporarily charged. Since air is a neutral substance, the positively charged hair can attract the air molecules, making the hair stand up even more.
Therefore, the statement "Friction caused a transfer of electrons between the slide and the child, making his like-charged hairs attract the air through induction" best describes why the child's hair stands up after sliding down the slide.
