Answer:

Option C, buoyant force has to be greater than the weight of the object

Explanation:

As per Archimedes' Principle, buoyant force is the force exerted by water and it acts in the upward direction and is equal to the weight water displaced by the object immersed in water. Hence, there arises three situations -

a) When both the buoyant force and weight of the displaced liquid is equal, the object remains in stable condition and thus it remains submerged.

b) When weight of water displaced by the immersed object becomes greater than the buoyancy force exerted by water, the object sinks down.

c) When weight of water displaced by the immersed object becomes less than the buoyancy force exerted by water, the object rise up and floats.

Hence , Option C is correct.

can someone please explain to me how to do this along with an example? will be giving brainliest if you help :)

Answer:

Whether matter exists as a solid, liquid or gas is determined by the arrangement of its particles and the strength of attraction between the particles. The three states can be easily distinguished because of their physical properties.

A physical property is a characteristic of matter which can be observed without any chemical change to the matter (shape, volume, colour, smell etc.). A chemical change is one in which new substance are formed.

Explanation:

Solids have a fixed volume and shape. They also vibrate in a fixed position. Ice

Liquids have do not have a fixed shape but a definite volume. They take the shape of their container. They are able to move past each other by allowing the liquid to flow. Water

Gases do not have a fixed shape or volume. Particles take up the space of the container they are in. Particles move freely and rapidly. Water vapour
