If Keiji and Nia are in a room where Keiji is standing on the floor and Nia is hanging upside down from a ceiling beam, and both have long hair that is not tied up, what difference would be noticeable in the way their hair behaves due to gravity?
Provide a very brief response.
Keiji's hair would fall downwards towards the floor due to gravity. This means that if his hair is long enough, it would touch his neck or shoulders. On the other hand, Nia's hair would also fall downwards due to gravity, but since she is upside down, her hair would point towards the ceiling, away from her head. If her hair is long enough, it would appear to be standing on end, reaching toward the ceiling beam to which she is attached.
