Two crates are submerged under water. 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 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.
2) 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.
3) 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.
4) 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.
I think it's 1 because buoyant force depends on the amount of water displaced and a sinking object displaces more water.
I think its answer 4
Actually, the correct answer is 2) 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.
The buoyant force exerted on an object immersed in a fluid, such as water, is equal to the weight of the fluid that is displaced by the object. This force opposes the force of gravity acting on the object.
In this scenario, since both crates are identical in size, they will displace the same amount of water. Therefore, they will experience the same buoyant force.
The weight or the material inside the crates does not affect the buoyant force acting on them, as long as the size and shape of the crates remain constant.
