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

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;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
