What, if any, of these collection and packaging techniques is incorrect? i. one individual should be designated as evidence collector to ensure evidence is collected in a consistent manner

ii. similar pieces of evidence are to be placed in shared containers, sealed and labeled.

iii. if there is a body, the collection of the body is done by the coroner or medical examiner

when the velocity of a mass on a spring is zero, the acceleration is at a maximum .

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
