Which types of numbers does scientific notation best describe?
1 answer:
The correct answer is
<span>c) very small and very large
Let's see this with a few examples:
1) if we have a very small number, such as
</span>
<span>we see that we can write it easily by using the scientific notation:
</span>
<span>2) Similarly, if we have a very large number:
</span>
<span>we see that we can write it easily by using again the scientific notation:
</span>

Answer:
<u>So the correct answer is letter e)</u>
Explanation:
The electric field of an infinite yz-plane with a uniform surface charge density (σ) is given by:
Where ε₀ is the electric permitivity.
<u>As we see, this electric field does not depend on distance, so the correct answer is letter e)</u>

<h2>Hello!</h2>
The answer is A. the principal energy level
<h2>Why?</h2>The principal energy level or principal quantum number n, tell us about the position of an determined electron in the energy levels relative to the greater average distance of an electron from the nucleus, the larger the value of n and the higher its energy.
The principal energy levels contains n sublevels, orbitals and
electrons.
For example, the number 1, has one orbital which is contained in a energy sublevel, its called s orbital, and it's just an orbital with 2 electrons.
Have a nice day!
