Investigators can use the angle of impact of blood spatter to help determine the direction from which the blood originated. By analyzing the angle, they can reconstruct the events that led to the blood spatter, helping to establish the position and movement of individuals involved in the crime. This information can provide crucial evidence to support or challenge witness statements and suspects' alibis.
To find the velocity after impact of a body with a fixed plane, you can use the principle of conservation of momentum. This principle states that the total momentum before the impact is equal to the total momentum after the impact. By setting up the momentum equation before and after the impact, you can solve for the velocity after impact.
The angle between two vectors a and b can be found using the dot product formula: a · b = |a| |b| cos(theta), where theta is the angle between the two vectors. Rearranging the formula, we can solve for theta: theta = arccos((a · b) / (|a| |b|)).
You measure it. Depending on the information provided, you can also calculate it, for example using trigonometry. ======================== Work done= Force vector . Displacement vector=Force*displacement*cos a, where a is the angle between the force and the displacement. So you have the values of work force and displacement then you can do the cosine inverse of the ratio of work done to the product of the force and displacement. That will give you the angle.

Rifling marks, the marks etched into a bullet as it travels through a gun's barrel, are to a gun as fingerprints are to a person. To see if a fired round came from a particular gun, the gun is test fired into a pool of water (to stop the bullet without changing its shape) then the marks on the test fired bullet and the bullet in question are compared. Knowing the trajectory of a bullet points you in the direction of its origination. There are also some clues that will help you determine from how far a shot was fired, such as approximate speed on impact and the presence of burnt gunpowder.
no ok no no it does not
Homicides, burglaries, kidnappings, arson, crimes against the people and many others. Pretty much, Criminal Investigators solve almost all of the crimes around.
Forensic science uses scientific methods to analyze evidence found at a crime scene, such as DNA, fingerprints, and ballistics. This helps investigators link suspects to crimes, establish timelines, and provide evidence for prosecution. By using forensic science, investigators can solve crimes by piecing together information from physical evidence.
How is biotechnology used to solve crimes? How is biotechnology used to solve crimes?
To solve crimes that have been done in the past.
nothin
yes
Forensic entomologists study insects that colonize decomposing human remains to estimate the time of death, help determine location of death, and provide other valuable evidence. By analyzing the insect activity on a body, entomologists can assist in solving crimes by providing crucial information to investigators.
lol hahaha
because it will separate the chemicals and give the investigators some evidence
