That change would be physical, since the chemical identity of the wood has not been altered by cutting it.

Unless you use something hot enough to burn the string it would only be a physical change.
Cutting paper into tiny pieces is a psychical change. This is because the chemical properties of paper are left unchanged and the paper is only reduced to a fraction of its original size, which only affects its physical properties.

Disintegration can be a chemical change, but it depends on what kind it is. For example, sharpening a knife is a physical change, but burning a piece of wood is a chemical change.
Foil cut into pieces represents a physical change.
burning of wood is a chemical change as it produces heat and cutting it into small pieces is a physical change as there is a change in shape and size.

No, it is a physical change. If you think about cutting the wood, the pieces will be smaller than the log, but they will have all of the same properties as they did when they were put together. An example of a chemical change is burning the wood. The act of burning it would be a chemical change since it is converting the wood into carbon and water vapor.

It is a physical phenomenon.
It is a chemical change, involving chemical reactions. Only water evaporation is a physical process.
It encountered a physical change.
