The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? a. gravity attracts only larger objects toward one another. b. gravity attracts larger objects only if they are close to one another. c. if the masses of the objects increase, then the force between them also increases. d. if distance between the objects increases, then the amount of force also increases.

' C ' is the only correct statement on the list.  We don't know anything about diagram-x or diagram-y because we can't see them.

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
