In atoms, electrons surround the nucleus in specific energy levels.
Answer: Option B
<u>Explanation:
</u>
Atom, actually considered as the tiny part that is ever present in this universe. Many theories and experiments were conducted, for studying what was present inside of an atom, and many theories came into light.
And finally, Bohr-Sommerfeld Theory stated the final conclusion, that the positive charge is at the centre of the nucleus, and all the electrons revolve in their specific energy levels. If an atom wants to move to lower energy state, it should emit energy, whereas for going to higher state, it should gain energy.

Answer:
Work = Energy . Distance . Cosθ
Explanation:
θ is a greek letter that means (in this formula) the angle between the Energy and the Distance.
If the Cosθ doesn´t show up in your formula, it is because the angle between the Energy and Distance is 0, and the Cos0 = 1
Energy . Distance . 1 = Energy . Distance
Answer:
mv=11700
m=900
v=11700/900=13m/s in west
