When you are in the front passenger seat of a car turning to the left, you may find yourself pressed against the right-side door. what concept(s) explain(s) why you press against the door and why the door presses on you?

1. newton's first and third law
2. just a centrifugal force
3.centrifugal force and newton's first law
4. centrifugal force and newton's second law

Newton's first and third laws. Every action has an equal and opposite reaction. Also, an object at rest, tends to stay at rest and an object in motion, tends to stay in motion unless acted upon by an outside force.

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
