So here are a series of experiments:1. A balloon was held against a wall. When it was released, the balloon fell to the floor. 2. A balloon was rubbed with a piece of wool and again held against a wall. This time, whenthe balloon was released it stuck to the wall. 3. A hole was poked in the bottom of a plastic cup. The cup was filled with water, and thewater was allowed to drain out through the hole in the bottom of the cup. While the water wasrunning out the bottom of the cup, a balloon was held near the stream of water. The watercontinued to fall straight down. 4. The previous demonstration was repeated, except this time the balloon was rubbed withwool before it was held near the stream of water. This time, the stream of water was drawntoward the balloon instead of falling straight down. Please explain all of the above.
