Nadia and Takumi are standing on a cliff edge overlooking the sea, when a consistent wind blows inland from the sea towards them. Nadia has long hair and is wearing a loose, lightweight scarf. Takumi is holding a helium-filled balloon on a string. What happens to Nadia's hair and scarf and the balloon when the wind blows? Respond very briefly.
Nadia's hair and scarf will be blown away from the direction of the incoming wind, meaning they will move towards and possibly across her face or over her shoulder, away from the sea. The scarf, being lightweight, might lift and billow out more than her hair. Takumi's balloon will also be pushed by the wind, but since helium makes the balloon less dense than air, it will not only move away from the sea but also rise upward. The string, if held tightly, will tilt in the direction of the wind as the balloon tries to move with the wind while being restrained by Takumi.
