two crates are submerged underwater. the crates are identical in size, but crate a is filled with iron and crate b has only air inside. which crate has a greater buoyant force acting on it?

1. crate b has a greater buoyant force acting on it because it is filled with air, so it will float. the object that floats will always have a greater buoyant force acting on it.

2. there is no way of knowing which object has a greater buoyant force acting on it until we can determine if they float. if both objects float, they have the same amount of buoyant force acting on them.

3. crate a has a greater buoyant force acting on it because it is filled with iron, making it heavier. buoyant force depends on the weight of the object.

4. both crates have the same amount of buoyant force acting on them because they are the same size and displace the same amount of water.
