Answer:
Ос. He used DNA testing to compare evidence to possible criminals.
Explanation:
Detective Scott worked to solve cases by the use of DNA testing which is an efficient way to solve a criminal case because DNA testing provides all information about the criminal. Due to this DNA testing, he solved many cases and the criminal caught with the help of this testing. If he can't use this DNA testing method then the case would not be solved.

Answer:
its c
Explanation:
the iron tail is away from the sun
106.5N
Explanation:
Given parameters:
Mass of cart = 75kg
Velocity = 4.4m/s
time taken = 3.1s
Unknown:
Force = ?
Solution:
To solve this problem, we are going to apply newton's second law of motion. The law states that "the acceleration of a body is directly proportional to the force on the body and inversely proportional to the mass".
F = m x a
F = force on body
m = mass of body
a = acceleration of the body
But we know that acceleration is the change in velocity with time of a body;
a = 
F = m x 
V is the velocity
t is the time taken
F =
= 106.5N
