Which statement explains why sugar dissolves easily in water, but sand does not?
Describe all of the forces acting on the ice cream in the root beer float. Relate these forces to the fact that the ice cream is floating.
The forces acting on the ice cream are gravity (weight) pulling downward and the buoyant force from the root beer pushing upward. Since the ice cream is floating, these forces are balanced (equal in size and opposite in direction), so the net force is zero.
