An atom is defined as having the same number of electrons (negative charge), protons (positive charge) and neutrons (no charge). This means that it will have the same amount of negative and positive charge, giving it a net zero charge. On the other hand, an ion has different amount of electrons and protons.
Answer:
18.4615385 amps
Explanation:
The voltage V in volts (V) is equal to the current I in amps (A) times the resistance R in ohms (Ω):
If there is no input to the system and no leaks from it, then the matter and energy in the system naturally does not change over time
Voltage is necessary for charge to flow
The radius of Earth's circular trajectory is
The time for the Earth to travel around the Sun is
Thus the velocity is velocity
From this we can deduce the centripetal acceleration
Angular velocity is
