<em>m</em> = 10.0 N/ = 10.0 kg
Answer:
Explanation:
1 Joule () is equivalent to . So, we have to make the conversion:
Joules KiloJoules
----
? ----------
The current is defined as the amount of charge Q that passes through a certain point of a wire in a time
:
But the charge Q flowing in the wire is just the charge of a single electron, e, times the number of electrons N:
so the current can be rewritten as
Using
,
(charge of one electron), and
, we find the current:
Therefore correct answer is A).
Solids
