Answer:
The magnitude of the force on an electron is 0.069 N.
Explanation:
Given that,
Distance between 1.70 A from the plutonium nucleus, 
The number of electron in iron nucleus is +26e.
To find,
The magnitude of the force between an iron nucleus.
Solution,
Total charge in the plutonium nucleus is, 
. The electric force between charges is given by :
F = 0.069 N
So, the magnitude of the force on an electron is 0.069 N. Hence, this is the required solution.
The answer is positive thoughts
Answer:
The horizontal speed of a projectile is constant for the duration of its flight. This is because, once launched, there are no horizontal forces acting on the projectile (air resistance is usually ignored because it is very small) so horizontally the projectile will travel at a constant speed. For any calculations involving the projectile's horizontal motion, we use
distance=speed×time
d=vt
So to solve this problem, we must convert units and then cancel units simultaneously:
Therefore we know that the distance that light travels in one year is 
inches.
