Answer:
3.6m
Explanation:
if you are at a building that is 46m above the ground, and the professor is 1.80m, the egg must fall:
46m - 1.80m = 44.2m
the egg must fall for 44.2m to land on the head of the professor.
Now, how many time this takes?
we have to use the following free fall equation:

where
is the height,
is the initial velocity, in this case
.
is the acceleration of gravity:
and
is time, thus:

clearing for time:

we know that the egg has to fall for 44.2m, so
, and
, so we the time is:

Finally, if the professor has a speed of
, it has to be at a distance:

and t=3.002s:

so the answer is the professor has to be 3.6m far from the building when you release the egg
Answer:
When equal and opposite forces meet each other, it results in motion and they would repel away from each other, causing the asteroid to be sent away from the earth.
Explanation:
Newton's Third Law states that every action has an equal and opposite reaction.
The first shell has 2 in and the second shell has 8 in therefore ypuvwont need to add anymore :-) so the answer is 0
Hello
the best answer is c
Answer: Option (c) is the correct answer.
Explanation:
Atomic number of hydrogen is 1 and one dot in its lewis structure displays only one electron. So, in order to complete its octet it needs one more electron.
Atomic number of carbon is 6 and its electronic distribution is 2, 4. Carbon needs 4 more electrons in order to complete its octet.
Atomic number of oxygen is 8 and its electronic distribution is 2, 6. In order to complete octet, oxygen needs 2 more electrons.
Atomic number of fluorine is 9 and its electronic distribution is 2, 7. In order to complete octet, fluorine needs 1 more electron.
Hence, we can conclude that out of the given options, lewis dot structure of oxygen atom needs 2 more electrons in its outermost shell.
