An electron in the Bohr model of hydrogen revolves around the nucleus to possess energy.
Answer: Option B
<u>Explanation:</u>
According to Rutherford, it was stated that electrons are the subatomic particles which revolve around the nucleus. But the error of spiral collapse of these electrons is due to absence of electrons in discrete levels. Hence, in Bohr atom model, the atom's negative or electrons are said to rotate in respective energy levels.
So, they keep on revolving around a nucleus in Bohr atom is said to revolve around a nucleus in order to possess energy. Thus, each level will exhibit discrete energy levels which will contain electrons of specific energy only.

Have a wonderful day :)
<span>According
to the special theory of relativity, all laws of nature
are the same in
reference frames that move at constant speeds.
That means that there's no test or measurement you can do to
detect whether you're moving at a constant speed</span> or how fast.
And THAT means that there's no such thing as "who's REALLY
moving" and "who's REALLY at rest". There's no such thing as
"real" motion, only motion relative to something else.

I'm pretty sure it is Edwin Powell Hubble and Albert Einstein
Explanation:
Answer:
Explanation:
From, the given information: we are not given any value for the mass, the proportionality constant and the distance
Assuming that:
the mass = 5 kg and the proportionality constant = 50 kg
the distance of the mass above the ground x(t) = 1000 m
Let's recall that:
Similarly, The equation of mption:
replacing our assumed values:
where
So, when the object hits the ground when x(t) = 1000
Then from above derived equation:
By diregarding
1000 + 0.981 = 0.981 t
1000.981 = 0.981 t
t = 1000.981/0.981
t = 1020.36 sec
