Explanation:

The task is to fill in the correct options from the figure below.

A whiplash is an injury to the upper spine caused by a violent j e r k of the head in either a backward or forward or side to side direction, resembling the motion of a whip.

1.As the child rides in the seat, his/her head and back rest against the padded back of the seat. If the car is brought to a rapid stop (as in a head-on collision) the child will continue to move *forward at the before-crash speed until he/she hits something.

2. The object hit is the back of the seat (supporting the entire back and head) which is padded and as a result the force *increases to the maximum value over a time interval.

3. Granted this time interval may be *small but that is considerably better than instantaneous. Also, since the head is supported, there will be no *whiplash.

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
