Answer:
The effect of this rotation on the person on the surface is the sky is moving, like an apparent diurnal motion.
Explanation:
<em>For an observer at a fixed position on Earth, the rotation of earth makes it appear as if the sky is revolving around the earth. In other words, if a person is standing for long enough in a field at night, it looks like the sky is moving, not the person. This motion is called "apparent diurnal motion." </em>
<em>Diurnal means having to do with a day, in a sense of a 24- hour period.</em>
Answer: Yes
Explanation: A molecule has a bond dipole but not have a molecular dipole.
Dipole moment: dipole moment is the product of the distribution of the charge of the molecules and the distance between of the molecules.
Example:
lets take an example of 
molecule in which two electro negative oxygen atoms are attached with Carbon atom. Oxygen being electro negative will attract the shared pair electrons towards itself and partial negative charge will create on oxygen atom and partial positive charge on carbon atom C.
due to formation of partial positive and partial negative charges dipole moment is created between oxygen and Carbon bond on both the sides in opposite direction.
Since, the dipole moment acting in opposite direction the net dipole moment in the molecule is zero.
Hence, Yes, a molecule has bond dipoles but not have a molecular dipole.
Yes, as long as it hasn't reached its maximum speed. Think of a car going 30mph, it can remain at this speed and travel at a constant rate; however, the car could also increase it's speed further. Hope this answers your question.
