<h2>Answer: Superposition</h2><h2 />
The superposition principle comes as a consequence of the <u>Coulomb's Law</u>, which describes <u>the force between two punctual electrical charges at rest</u>. However, Coulomb's law does not tell us anything about what happens if we have <u>more than two electrical charges</u> or if they are not punctual.
For example, if we have three charges aligned and we want to find the force on one of the ends and how the presence of the central electrical charge influences. The evidence from the experiments has shown that this central charge does not affect the force between them, and this can be expressed by the superposition principle which, in other words, is:
<em>Given a system of punctual charges, the electric force on each of them is the vector sum of the forces due to each of the other charges, as if the rest of the charges were not present.
</em>
That is, we can calculate each term by Coulomb's law ignoring completely the existence of other charges.
<h3>Intramolecular Forces:-</h3>
An intramolecular force (or primary forces) is any force that binds together the atoms making up a molecule or compound, not to be confused with intermolecular forces, which are the forces present between molecules.
Answer:
<em>W=700 Joule</em>
Explanation:
<u>Physics Work
</u>
Is the dot product of the force vector by the displacement vector
When both the force and the displacements are pointed in the same direction, the formula reduces to its scalar version
The weightlifter is applying a net force of 350 N to lift the weights a distance of 2 m, thus the net work done is
According to the theory of evolution, _favorable_ traits will become common in a population over time.
"Favorable," that is in a survival sense. Remember, all that matters [to the genes] is for the individual to function and survive long enough to reproduce, and thus continue those genes into a new generation, the offspring. Natural selection finds certain adaptations "favorable" if they aid in the individual's ability to survive long enough to reproduce. Evolution, on the other hand, looks at a population and how over time these favorable genes change the individuals' genetic makeup within that population.
