Final answer:
The 8.0 lb blowing ball will sink when lowered into water.
Step-by-step explanation:
The answer to the question is B. Sink.
When an object is placed in a fluid, such as water, it experiences a buoyant force. If the buoyant force is greater than or equal to the weight of the object, the object will float. However, if the weight of the object is greater than the buoyant force, the object will sink.
In this case, the weight of the 8.0 lb blowing ball is greater than the buoyant force exerted on it by the water. Therefore, the ball will sink when lowered into water.
