It means every thing is made out of Atoms and some things are element componds so elements are the "backbone" of the compounds.
Answer:
The kinetic energy will be "399.65 J".
Explanation:
Given:
Mass,
m = 1.2 kg
Velocity,
v = 31.3 m/s
The total energy of mass will be:
⇒ 
or,
⇒ 
By putting the values, we get
Since,
The system's total energy is unchanged, then
⇒
or,
⇒ 
Falling water that turns a turbine
<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
</span>
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!!!!
