The length of time it takes to complete one full rotation
The planet's rotational period is the only thing that determines the length of one day. (mostly - it also is dependent on how fast the planet orbits the sun. If it orbits quickly, the "day" will be measurably less than the time for one full rotation.)
Everywhere: the length of the day is always 24 hours irrespective of latitude & longitude since the angular rotation of the planet is 360º per 24hours. The DAYLIGHT length changes seasonally and proportionally to latitude, but the DAY length is constant.
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.
The length of a day on a planet is how long it takes to spin on its axis. The length of a day on Mercury is 58 days and 15 hours in Earth time. A day on Venus is 243 Earth days, Mars is 24 hours 39 minutes and 35 seconds, Jupiter's day is 9.9 Earth hours, Saturn is 10 hours and 47 minutes, Uranus is 17 hours 14 minutes and 24 seconds, and Neptune's day is 16 hours 6 minutes and 36 seconds.
Mars. Its day-night cycle is only about 40 minutes longer than Earth's.
No
Because of the difference in speed of rotation of each planet.
Mars
Mars.
Yes; the faster the planet rotates, the shorter its day will be.
Take the length of the planet's orbit, divide it by the speed at which the planet is orbiting and VOILA! The "year."
by the rotation of the planet
It is the rotation of the planet one complete revolution that determines the length of a day.
the tilt of the planet
er..24 hours... what planet do you live on?
mars
How long it spins on it's axis
