Being made mostly of gas is NOT a
characteristic of an inner planet. The correct answer between all the choices
given is the last choice or letter D. I am hoping that this answer has
satisfied your query and it will be able to help you in your endeavor, and if
you would like, feel free to ask another question.
False: because atoms are base on the elements on the periodic table.
The current is defined as the ratio between the charge Q flowing through a certain point of a wire and the time interval,
![\Delta t](https://tex.z-dn.net/?f=%5CDelta%20t)
:
![I= \frac{Q}{\Delta t}](https://tex.z-dn.net/?f=I%3D%20%5Cfrac%7BQ%7D%7B%5CDelta%20t%7D%20)
First we need to find the net charge flowing at a certain point of the wire in one second,
![\Delta t=1.0 s](https://tex.z-dn.net/?f=%5CDelta%20t%3D1.0%20s)
. Using I=0.92 A and re-arranging the previous equation, we find
![Q=I \Delta t= (0.92 A)(1.0 s)=0.92 C](https://tex.z-dn.net/?f=Q%3DI%20%5CDelta%20t%3D%20%280.92%20A%29%281.0%20s%29%3D0.92%20C)
Now we know that each electron carries a charge of
![e=1.6 \cdot 10^{-19} C](https://tex.z-dn.net/?f=e%3D1.6%20%5Ccdot%2010%5E%7B-19%7D%20C)
, so if we divide the charge Q flowing in the wire by the charge of one electron, we find the number of electron flowing in one second:
