Respuesta :
Answer: The density of the ice cream and buoyant.
Explanation:
The density of the ice cream plus buoyant will cause the carbonation in root bear will cause gravity to push down on the ice cream and buoyant pushes the ice cream upwards, the ice cream floats because the buoyant force is greater than the weight of the ice cream.
Answer: The root beer exerts a force on all sides of the ice cream. These forces are all equal and cancel each other out. Gravity pushes downward on the ice cream. This can also be called the weight of the ice cream. Buoyant force pushes the ice cream upward. The ice cream floats because the buoyant force is greater than the weight of the ice cream.
