If Keiji and Yuna are standing on their heads, and Keiji has a ponytail while Yuna is wearing a loose skirt secured at the waist, what will happen to Keiji's ponytail and Yuna's skirt due to gravity? Respond very briefly.
Keiji's ponytail will fall downward towards the ground, which now means it will be pointing away from his feet due to gravity pulling the hair towards the Earth. Yuna's skirt, being loose and not secured around her legs, will also fall downwards toward the ground due to gravity, which would result in the skirt draping around her waist and torso rather than her legs, potentially revealing her legs, depending on the length and cut of the skirt.
