The length of the day would change if either the rotational speed of the the planet or the orbital distance from the sun changed.
However, if you mean what factors affect the length of daylight, then that is different.
There would be no seasons, and the length of day & night would be exactly 12 hours each.
Not at all. The planet's daily rotation is independent of its distance from the Sun.
The length of a "day" on the moon is 29 Earth days.
Nothing - the length of 'day' on any planet - is the time it takes to revolve once on its axis. Relating to the Earth - that's approximately 23 hours 56 minutes.
29.5 earth days is one moon day wich is the length of the moons day
The length of day does not affect the season.
It would have zero effect.The length of a day is determined by one's location on the planet.
the tilt of the planet
If the earth rotated from east to west at 1 quarter each present rate how would this affect rising and setting of the sun and the lenght of the day?
If a day took 40 hours, then a day would take 40 hours.
It takes 24 hours (the length of one day) for the Earth to rotate once. If the rotation sped up, the length of a day would shorten.
If the sun increases in size but nothing else changes, then there will be no change in the lengths of day and night. However, the gravitational and tidal effects of changes in the sun's size is likely to affect the earth's rotational period and its orbit.
I think the length of day affects humans by sleeping earlier or later, they can also be affected by having different emotions. But I think I'm wrong...

In that case, the length of the day would also be approximately 40 hours.
