Answer: Moon is much smaller in size and has very less mass, when compared to our mighty earth and there is absence of strong magnetic field on the moon which could protect from the incoming solar radiation from the sun. Since there is no magnetic field, it can swipe off any materials that are present there on the moon, diminishing the atmosphere.
This is the reason why moon does not have any atmosphere.
The intermolecular force attracts of the stearate ion in the oil drop.
<u>Explanation:</u>
- Dispersion force is the intermolecular force that attracts the stearate ion to the oil drop. The weak force with temporary dipoles. This force is referred to as induced dipole attraction.
- The Dispersion is meant as an electron in two atoms occupies the position and this force is called induced dipole attraction.
- The Dispersion force depends on the atomic and molecular weight of the material.
Drop "moves" from the list for a moment.
You can also drop "stops moving", because that's included in "changes speed"
(from something to zero).
When an object changes speed or changes direction, that's called "acceleration".
I dropped the first one from the list, because an object can be moving,
and as long as it's speed is constant and it's moving in a straight line,
there's no acceleration.
I think you meant to say "starts moving". That's a change of speed (from zero
to something), so it's also acceleration.
