They are not the same event in that they occur in different places and times in most frames of reference. In the photon's frame they are not separated in either space nor time because photons don't experience time and at least mathematically all points on the spacetime manifold are the same point to a photon. What the zero spacetime interval can tell us though, is that the events are connected by a light beam (light-like separation). There is as much time between the events as there is space and one event can conceptually cause the other. They are on the cusp between time-like and space-like events.
Good conductors of electricity have larger conductivity values than insulators.
A material that obeys Ohm's law reasonably well is called an ohmic conductor or a linear conductor.
The resistance of a conductor is proportional to the conductivity of the material of which the conductor is composed.
Answer: Options 1, 2 and 4.
<u>Explanation:</u>
In physics and electrical engineering, a conductor is an article or kind of material that permits the progression of charge in at least one headings. Materials made of metal are basic electrical conduits.
Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them. Most atoms hold on to their electrons tightly and are insulators.
The answer is
D. Kinetic energy
