:? If someone could help me that would be great. I am upgrading and currently I am enrolled in Physics 20. Our teacher decided to throw this at us when we haven't looked at buoyancy at all, so I was hoping someone could help me. This question probably sounds silly but I haven't encountered any of this yet and it is not making sense to me. Here is goes:

Weight of suspended mass (N) - Just under 5N

Weight of mass in water (N) - Just under 4.3 N

Initial volume of water - 1.40 L

Final volume of water - 1.55 L

1. Calculate the buoyant force of water on the mass.

2. From the values above, calculate the volume and weight of water displaced. Compare the weight of the volume of water displaced with the buoyant force acting on the submerged mass calculated in question 1. If the values are different, describe sources of error to account for the difference.

Application:

1. Tim and Susan are floating on an inflatable raft in a swimming pool. What happens to the water level in the pool if both fall off the raft and into the water? Explain your answer.
