What is the responsible length of one day?
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.)
What location always has the same length of day?
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.
What factors would affect the length of the day?
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.
How long is one day on each planet?
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.
Which planet has a day that is most similar in the length to a day on Earth?
Mars. Its day-night cycle is only about 40 minutes longer than Earth's.
Does each planet have the same length of day?
No
Why does the length of the day and night vary from planet to planet?
Because of the difference in speed of rotation of each planet.
What planet's length of its day is close to the length of Earth's day?
Mars
What planet length in day is close to the length of earths day?
Mars.
What is the relationship between the length of a planet's day and the rate of planet's rotation?
Yes; the faster the planet rotates, the shorter its day will be.
How do you work out the length of 1 year for each planet?
Take the length of the planet's orbit, divide it by the speed at which the planet is orbiting and VOILA! The "year."
What would you define the length of a planets day?
by the rotation of the planet
What movement of the planet makes one day as a unit of time?
It is the rotation of the planet one complete revolution that determines the length of a day.
How does the movement of the earth affect the length of its day and its year?
the tilt of the planet
What is the length of day for earth?
er..24 hours... what planet do you live on?
Which planet has a day almost the same length of time as earth?
mars
What determines the length of day on a planet?
How long it spins on it's axis
