The current is defined as the amount of charge Q that passes through a given point of a wire in a time 
:
Since I=500 A and the time interval is
the charge is
One electron has a charge of
, therefore the number of electrons that pass a point in the wire during 4 minutes is
electrons
Since I=500 A and the time interval is
the charge is
One electron has a charge of
Explanation:
The given data is as follows.
Angular velocity () = 2.23 rps
Distance from the center (R) = 0.379 m
First, we will convert revolutions per second into radian per second as follows.
= 2.23 revolutions per second
=
= 14.01 rad/s
Now, tangential speed will be calculated as follows.
Tangential speed, v =
= 0.379 x 14.01
= 5.31 m/s
Thus, we can conclude that the tack's tangential speed is 5.31 m/s.
