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: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
