Question

Your friends tell you that all heavy objects sink in water. Do you agree or disagree? Explain your answer in terms of buoyant force.

Answer 1

Answer:

Disagree

Explanation:

Concept of sink and float depends on the condition of water displaced by the objects

As we know that object will float when the weight of the object is less than the buoyancy force on it.

Also we can say that buoyancy force is the net upthrust applied by the water on the object.

This upthrust is equal to the weight of water that is displaced by the object.

So if heavy object displace more amount of water so that the weight of displaced water is more than the weight of the object then it must float on the water.

so this is not true that all heavy objects sink in water.

Answer 2

Disagree because its not about how heavy the object is and you don't know exactly how heavy, heavy is and the weight doesn't matter, its density that matters
