1. Rusting is an oxidation reaction of iron.
2. The mass of an object increase after rusting.
Rusting is a chemical reaction known as oxidation. When a metal object rusts, it gains mass because the iron in the metal reacts with oxygen to form iron oxide (rust). The mass of the object after rusting will be greater than its original mass due to the addition of the iron oxide.
The mass would be greater
To accelerate the rusting process of an object quickly, you can expose it to moisture and oxygen, as well as salt or acidic substances. This will speed up the chemical reaction that causes rust to form on the object.
Rusting of iron is a chemical process, an oxydation reaction.
yeah it actually depends upon the "material" you have taken, if it is so large then it will make no difference. but if you want exact measurement, then its mass will remains constant. rust will fulfill the deficiency in mass of that material. If we remove the dust then its mass will obviously decreases.
The reaction force acts on the object causing the original force, not on the object the reaction force is caused by. So there is only one force acting on each object, and they both move (unless there is another force outside this pair preventing such movement).
A convex mirror produces virtual upright images that are smaller than the original object. The image is located behind the mirror, and its size is reduced compared to the object.
Rusting of objects can be prevented by using protective coatings such as paint, oil, or galvanization to create a barrier between the object and oxygen and moisture in the air. Keeping objects dry, storing them in a low-humidity environment, and using desiccants can also help prevent rusting. Regular maintenance, such as cleaning and lubricating, can further protect objects from rust.
An example of why it is easy to miss an action-reaction pair is when one of the objects involved in the interaction is much more massive than the other. The reaction of the heavier object may cause a small and less noticeable effect on it compared to the action of the lighter object.
action = reaction, but they works in the different object
Earth can push and object forward with a reaction force
When pulling an object on a table, the reaction force will be equal and opposite to the pulling force exerted on the object. When pushing an object on a table, the reaction force will be equal and opposite to the pushing force exerted on the object. In both cases, the table exerts a reaction force to prevent the object from moving.
