At any crime scene, the two greatest challenges to the physical evidence are contamination and loss of continuity.
<h3>What is the meaning of physical evidence?</h3>
In evidence law, physical evidence (also called real evidence or material evidence) is any material object that plays some role in the matter that gave rise to the litigation, introduced as evidence in a judicial proceeding (such as a trial) to prove a fact in issue based on the object's physical characteristics.
The two types of evidence at crime scenes:
Biological evidence (e.g., blood, body fluids, hair and other tissues)
Latent print evidence (e.g., fingerprints, palm prints, footprints)
The biggest impediment to an investigation is the removal or loss of a piece of evidence from the scene of a crime.
Hence, at any crime scene, the two greatest challenges to the physical evidence are contamination and loss of continuity.

Answer:
9.97sec
Explanation:
To solve for the period we can derive the formula as follows
ω=2πf
ω=2π/T
v=rω
v=2πr/T
T=2πr/v
T=9.97sec
A black sweater. Why? Because black is the most absorbent color while as white is reflecting the light. Hope this helps...
Answer:
Current that flows through any one of the resistors has a value of 12 amperes.
Explanation:
When a group of resistors are connected in series, the same current flows through each resistor. According to the Ohm's Law, the circuit can be represented as follows:
Where:
- Voltage of the battery, measured in volts.
, , - Electric resistance of the first, second and third resistors, measured in ohms.
- Current, measured in amperes.
If , then:
Current that flows through any one of the resistors has a value of 12 amperes.
False, friction produces heat, kinetic energy has been changed to heat energy.
