To an observer on the moon able to see earth how long would one full cycle of earth phases be?

It would be about 29.5 earth days. Or, precisely the same length of time as a full cycle of moon phases.

Why would an observer on the Earth see a complete cycle of the phases of the moon in approximately one month?
because of the tilt of both the moon and the earth on their rotation axis
How would the Moon appear to an observer in space during its revolution Would phases be observable Explain?
During the Moon's revolution, an observer in space would see the moon, but would not be able to see it spin around. From far to the north, about the solar system, the moon would appear to make a squiggly
What planets are seen in phases like the moon?
Both Mercury and Venus, being closer to the sun than us, will show phases. When Venus is at is brightest it is generally just a bit over half full. If you were on Mars, you would note phases on earth.
How would the moon appear to an observer on earth if the moon did not rotate?
it would still appear to rotate
How does the moon appear to an observer on earth during a full moon?
Full, large or whole. Maybe the question was meant to be...How would the Earth appear to an observer on the moon during a full moon?

How the moon would appear to an observer in space during its revolution. Would phases be observable?
Yes. Unless the observer was on the back side of the moon, or on the opposite side of the earth from the moon, he/she could see the same phases that we see here on earth.
If you lived on Mars would Earth exhibit a full cycle of phases?
No, because the Earth does not orbit around Mars. The Moon only has phases because it orbits around Earth.
Is there a relationship between moon phases and earth phases?
Yes. If you're standing somewhere on the moon's half-surface that always faces the earth, then the earth is always in your sky, and you see it go through a cycle of phases every 29.53 days, just as the moon does in our sky. But the shapes of the phases that the earth displays to an observer on the moon are exactly opposite the sequence of shapes that we see the moon display. The result is that the illuminated portion of the moon in earth's sky, plus the illuminated portion of earth in the moon's sky, always add up to exactly one fully illuminated disk.
Would you see phases of the earth from the moon?
Yes.
What would be the effect if the earth were slightly further from the sun?
-- earth's orbital speed would be slightly less -- earth's orbital period (the "year") would be slightly longer -- every climate on earth would be less warm -- the period of the complete cycle of moon phases would be slightly shorter -- the length of the solar day would be slightly closer to the earth's period of axial rotation

Do moons on other planet give light as earths moon?
The planets closer to the sun than we are (Mercury and Venus) show all the same phases that the Moon does. The planets that are farther away don't show all the phases, they are either full or pretty close to full. The reason is that to get a "new" phase, the planet or moon must be between the Earth and the Sun. Mercury and Venus can come between the Earth and the Sun and be in the "new" phase, but the outer planets can't.
How is a lunar and solar eclipse alike?
Both lunar and solar eclipses are the result of positioning 3 astronomical bodies (earth, sun and moon) in a straight line relative to the observer. A solar eclipse is observed when the sun, moon, and earth are positioned in a straight line with an observer on the earth. A lunar eclipse is observed when the sun, earth, and moon are in a straight line with an observer on the earth. A lunar eclipse, as observed by an observer on the earth would appear as a solar eclipse as observed by an observer on the moon.
