Atomic structure applies to just that, atoms in isolation. Witness looking at atomic spectra using laboratory discharge tubes to ionise low pressure gases of atoms of the elements you want to examine for energy level structure (sodium and the yellow D line "doublet").Crystal structure applies to vast collections of atoms/molecules/ions in complicated geometrical arrays which form lattices. Simple cubic, body centred cubic, face centred cubic being a few "simple" examples.
Answer:

Explanation:
Please find the image for the question as attached file.
Solution -
Given -
First of all we will calculate the velocity at point C,
As per newton's third law of motion-

Substituting the given values in above equation, we get -

Now we will determine the radius of curvature for the curve shown in the attached image

Differentiating on both the sides, we get -
meter
Acceleration on curved path

Final acceleration

Resident 4 is the correct answer.
The Moon always rotates about the Earth in its orbit. The position of the Earth, moon and sun during a new moon is Earth is in between Sun and Moon.
<h3>What is new moon?</h3>
When moon has travelled for 14 days, it starts its journey again for the next 14 days. The journey starts from the new moon to the full moon. The position of new and full moon is the same. At this time, the Earth is in between the Sun and the Moon.
Thus, the position of the Earth, moon and sun during a new moon is Earth is in between Sun and Moon.
