Activity is given by
The activity N//t of the radioactive source is 426136363636.36365 Bq
It would be Atoms, they’re all made up of these tiny particles
The the drift velocity of the electrons is determined by atom vibrations in the crystal lattice.
<h3>How to explain the information?</h3>
Assume we could increase the average time between collisions in a typical metal to get to a limit of zero resistance. The free electrons would therefore be continuously accelerated by a constant applied voltage, according to the classical paradigm of conduction. Both the current and the drift speed would gradually pick up over time.
Although it is not the scenario implied by the question, it is possible to switch to zero resistance by using a superconducting wire instead of the usual metal. In this scenario, the maximum current is constrained, the drift velocity of the electrons is determined by atom vibrations in the crystal lattice, and it is difficult to produce a potential difference across the superconductor.
