<span>Coulomb's law describes the magnitude of the electrostatic force between two electric charges.
The Coulomb's law formula is:
<span>F = Ke * q1 * q2 / r2</span>
Where:
q1: Charge of object 1
q2: Charge of object 2
r: Distance between the two objects
F: Force between the two objects. A positive force implies a repulsive interaction, while a negative force implies an attractive interaction
Ke = Coulomb Constant, 8.9875517873681764 * 109 N.m2.C<span>-2

Coulomb's Law Examples:
What is the magnitude of the force between two protons which are 1.6E10-6 meters apart?
The charge of 1 proton is +1e (+1.602E-19 C).
F = 8.9875517873681764 * 109 * 1.602E-19 * 1.602E-19 / (1.6E-6 * 1.6 E-6) = 9 * 10-17 N

f = k (q^1)(q^2)/r^2
both sides by r^2 Multiply
fr^2/r^2 = kq^3/r^2
both sides by r^2 divide
f = kq^3/r^2
Answer:
f = kq^3/r^2
Hope this helps!!!!

Answer:
D. All lunar eclipses reoccur.
Explanation:
Every Saros cycle (19 eclipse years)
Saro was described by Edmond Halley arround the year 1691, which is a period of 223 synodic which can be interepreted as "repitition" it is used by the scientist for eclipse prediction either for the sun or moon eclipse. It is 18years and 11days and some hours.
It should be noted that with this All lunar eclipses reoccur.
the state or quality of being efficient.
"greater energy efficiency"
Answer
Efficiency is the ability to avoid wasting materials, energy, efforts, money, and time in doing something or in producing a desired result.
Either of them is. 1/(the other one). That's 'C' .
Whole grains are good carbs so it would be true.
And the easiest would be carbohydrates.
