phases
The direction is is lit from. When the Moon is lit (by the Sun) from straight on it appears full, when it is lit from behind it appears new, and when it is lit from the side it looks like a semi-circle.
YES.
The sun is always in different places at different times.
cuz the the planets are different distances away from the sun and its times are way different
the sun follow the celestial sphere
That is the property of thermoplastics. If they could not be formed into different shapes many many times then nobody would bother to make them.
Multiply length times width if the shape is a rectangle. Other shapes have different formulas.
.... no. ----------- I presume you are asking this because you have watched the horror movie called 'Teeth'. The answer is no, a vagina can never have teeth. The myth, as perceived in the movie known as 'vagina dentata' originated from the hymen (a skin-like membrane that is attached to the inner vulva) having naturally different shapes or openings, that at times could be a bit jagged and give the appearance of teeth.
Only in a vacuum. In air the air resistance will be slightly different on items of different shapes and therefore they will land at slightly different times
Variables or data
We see the moon differently at different times because it moves around us, and we spin around. We are looking at it from different angles
It really depends on the shape. Different shapes have different relationships between perimeter and area. For similar shapes, the perimeter will increase linearly with the diameter, length, or any other linear measure, while the area will increase with the square of any linear measure. For example, if one square has ten times the side-length of another, its perimeter will also be ten times longer; but its area will be 100 times larger.
Taking, for example, the following variant words to be 'different' father fathers father's fathers' fatherless there are 12,842 'different' words, which range in frequency of appearance from once to 63,924 times.
Temporal Isolation
In the King James version the word - appearance - appears 38 times the word - appearances - appears twice
The direction is is lit from. When the Moon is lit (by the Sun) from straight on it appears full, when it is lit from behind it appears new, and when it is lit from the side it looks like a semi-circle.
That is called "crop rotation".
