Below:
Explanation:
Consider two rays originating from the bottom of the pond. As these rays get refracted into the air, they bend away from the normal. ... This point gives the apparent position of the bottom of the pond, therefore, the pond appears to be shallower.
Hope it helps....

<u>Answer:</u> The word for the definition of an electron in the highest occupied energy level of an atom is " valence electron".
<u>Explanation:</u>
A valence electron is an external shell electron associated with an atom in chemistry and physics that can participate in the creation of a chemical bond if the highest occupied energy level of an atom is not closed. All atoms in a single covalent bond add one valence electron to form a mutual pair.
The periodic table showcases the arrangement of valence electrons group and block wise like:
- Alkali metals have <em>n </em><em>s</em> 1 as external shell configuration like H, Li, Na, K etc.
- Alkaline metals have <em>n</em> s 2 as external hell configuration like Be, Mg, Ca etc.
- p-block comprises group 13 to 18 having general electronic configuration <em>n </em><em>s</em> 2, <em>n</em><em> p</em><em> </em>1–6.
- d-block or transition metals have general electronic configuration (<em>n</em>-1) d 1–10, <em>n </em>s 1–2.
- f-block or inner transition metals have general electronic configuration (<em>n</em>-2) f^1–14 (<em>n</em>-1) d^0-1 <em>n </em>s^2.
Answer:
Explanation:
<u>Instant Velocity
</u>
Given the position as a function of time x(t), the instant velocity is the derivative of the function:
We are given the position as
The derivative of x is
A) Let's compute v(0)
B)
C)
D)
The question is poor.
It expects you to choose 'B', but things aren't nearly that simple.
We picture all of the asteroids bunched up in a neat bunch between
the orbits of Mars and Jupiter, with each asteroid following its own
nearly circular orbit. But many asteroids have wildly non-circular
'eccentric' orbits, sometimes being closer to the sun than the Earth is.
You know how you hear so much discussion about when did the Earth
get hit by an asteroid ? and when will the Earth be hit by another asteroid ?
and what will happen when the Earth is hit by an asteroid again ? None
of that would be possible if asteroids all had nearly circular orbits.
We picture comets as having these loooong skinny orbits, spending
most of every orbit waaay out in the solar system, and then dipping
close to the sun for a few days, and then going back waaaay out again.
But there are also many comets in nearly circular orbits around the sun.
You never hear anything about them, because you can never see them
without a powerful telescope, and they never do anything exciting.
So some comets could be a correct answer to this question too.
And since meteoroids are the remains of old comets, and follow the
orbit of the comet that they chipped off from, there are a lot of meteoroids
in circular orbits too, and they could also be a correct answer to this question.
