Which statement best summarizes the central idea of “Applications of Newton’s Laws”? Newton’s laws can explain the forces that occur between objects every day. Newton’s laws are useful for explaining why we should make good decisions. People should use caution when moving objects, due to objects’ inertia. Newton’s laws are outdated and cannot be used for present-day problems and situations.

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
