Which non-destructive technique is used for analyzing carpet fibers at a crime scene ?

On my test i put    forensic  fingerprint and it said correct but idk if were on the same test  but thats what i put.

This is what i found on google “kinetic energy. energy is transferred from one object to another when a reaction takes place. energy comes in many forms and can be transferred from one object to another as heat, light, or motion, to name a few. this energy would be in the form of motion, with the person lifting the blue ball to a higher level.” i hope this you
