Answer:
Time = 80.91 seconds
Explanation:
Given the following data;
Velocity = 5.50 m/s.
Distance = 445 meters
To find the time;
Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.
Mathematically, velocity is given by the equation;
Substituting into the formula, we have;
5.5 = 445/time
Time = 445/5.5
Time = 80.91 seconds
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
