Final answer:
When a rubber duckie falls into a bathtub, it displaces water, experiences a buoyant force, and creates a downward force on the bottom of the tub.
Step-by-step explanation:
When a rubber duckie falls into a bathtub, several things happen:
- The duckie displaces some water, causing it to move out of the way and make room for the duckie.
- The duckie experiences a buoyant force, which is the upward force exerted by the water on the duckie.
- The weight of the duckie creates a downward force on the bottom of the tub, exactly equal to its weight.
Overall, the duckie sinks to the bottom of the bathtub due to its weight, but it also experiences an upward buoyant force from the water. The downward force on the bottom of the tub increases by the weight of the duckie.
