Answer:
Explanation:
For this case we have the following info given:
Number of Na+ ions 
Each ion have a charge of +e and the crage of the electron is 
The time is given 
if we convert this into seconds we got:
Now we can use the following formula given from the current passing thourhg a meter of nerve axon given by:
Where N represent the number of ions, e the charge of the electron and Q the total charge
If we replace on this case we have this:
And from the general definition of current we know that:
And since we know the total charge Q and the time we can replace:
The current during the inflow charge in the meter axon for this case is 
<span>1.an electric is induced when you move a magnet through a coil wire
2.a greater electric current is induced if you add more loops of wire</span>
As for me, there are two suitable answers for the question represented above and here is a short explanation why I consider these two to be correct :
D. The horizontal velocity of the projectile and <span>B. The length of time before it lands
</span>
-- this led me to answers! Hope everything is clear! Regards!<span>

<span>According to the three laws of planetary motion, planetary orbits are in the shape of an "Ellipse"
In short, Your Answer would be Option B
Hope this helps!</span>
Kinetic energy= 1/2 m v^2
so... 1/2(1350)(12^2)
kinetic energy = 97200Joules
