During a game of hide and seek, Ravi decides to hide by hanging upside down from a tree branch. His long hair is not tied back. Mina is seeking and she comes across Ravi's hiding spot. What does Mina see in regard to Ravi's hair, and why? Make your response very short.
Mina sees Ravi's hair hanging toward the ground away from his head. Gravity pulls objects towards the center of the Earth, so when Ravi is upside down, his hair, which is not anchored to anything other than his head, is pulled downwards by gravity. This effect makes Ravi's hair point straight down towards the ground rather than lying flat against his head.
