In a room with a single window on one wall, Ravi and Keiko are standing at opposite ends. A gust of wind rushes in through the window, blowing directly towards Keiko. Ravi is wearing a loose hat, and Keiko is holding a balloon. What happens to the hat and the balloon as the wind blows in?
Provide a very brief response.
The wind exerts pressure on objects in its path. Ravi's loose hat is likely to be blown off his head as it is not securely fitted and offers little resistance to the moving air. On the other hand, Keiko's balloon, being lighter and more buoyant, will be pushed forward by the wind but may not travel in a straight path due to its tendency to bob and weave in the air currents. The balloon could move erratically or even be pushed upwards if the force of the wind is strong enough and hits it from below.
