Respuesta :
To calculate the amount of charge in coulombs moved by the car battery, we use the formula
[tex]Q = Nq_{e}[/tex]
Here, N is the number of electron and [tex]q_{e}[/tex] is the charge of electron.
Given [tex]N=1.27 \times10^{21} electrons[/tex] and we know [tex]q_{e} =1.6\times10^{-19} C/electrons[/tex]
Substituting these values in above formula we get,
[tex]Q=1.27 \times10^{21} electrons\times 1.6\times10^{-19} C/electrons\\\\Q=793.8C[/tex]
Solution:
According to the question we have to use the formula Q=ne
Since we have given
q=1.6*10^(-19) and the car moves the electrons is 1.27*10^21
thus for calculation
1.27*10^21*1.610^(-19)
=2.03*10^3C
=203C
