First analyze the force that is acting on each charge. The force is determined by the two. objects interacting. If you start with Case 1, the charges are q and 4 q with a separation of d. That means. the force is 4kqq/d2 .
DNA is the most powerful tool available for identification in forensic investigations. Because of its ability to link physical evidence found at a crime scene to a single person, it is often referred to as a âdigital fingerprint.â This method is so precise that it can ensure pinpoint accuracy, down to one in a billion.
DNA profiling (also called DNA testing, DNA typing, or genetic fingerprinting) is a technique employed by forensic scientist s to assist in the identification of individuals by their respective DNA profiles.NA profiles are encrypted sets of numbers that reflect a person's DNA makeup, which can also be used as the person's identifier. DNA profiling should not be confused with full genome sequencing. It is used in, for example, parent testing and criminal investigation.
