The graph of mass versus kinetic energy shows that mass is proportional to kinetic energy. In other
words, as the mass of the car increases, its kinetic
energy increases at the same rate.

Consider two cars, with the second car having a
mass six times the mass of the first car. Compare
the kinetic energy of each car. Then describe the
implications of your answer for using brakes to
bring each car to a complete stop.

overcharge is the right answer system

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
