If the Earth to moon distance were greater than the Earth to sun distance would an observer on Earth be able to see the Moon in it's first quarter phase?

If you mean "Could we see the changes in the moon's apparent shape ?", that's doubtful.
Consider Venus:
-- When Venus is closest to the earth, its distance is only about 1/4th the distance from us to the sun.
-- Venus' diameter is about 3 and 1/2 times the diameter of the moon.
-- Venus goes through a full set of phases as seen from earth, but even with its comparatively large size
and at that comparatively short distance, we can't see them without a telescope.

Which is closer to New York the moon or Paris and is any distance on Earth greater than the distance to the moon?
Paris. The moon is about 220,000 miles away from Earth. Earth's circumference is about 25,000 miles. Paris is much closer to New York (3,636 miles) then the moon (238,857 miles). No distance between two places on Earth is greater than the distance to the moon. The circumference of the Earth is only 24,901 miles so that's pretty much the furthest you can go between two points on Earth. The distance to the moon as mentioned is over 238,857 miles.
Is it true that Earth's gravitational pull on a spacecraft is greater as the spacecraft moves away from Earth?
False. The attractive force of gravity decreases with the square of the distance.
Is Africa greater in distance east to west or north to south?
Africa is greater in distance from north to south. This distance is approximately 5,000 miles. From east to west, Africa is approximately 4,600 miles.
Where is the moon located during an annular eclipse?
No - the Earth's shadow (at the distance of the Moon) is much larger than the diameter of the Moon.No - the Earth's shadow (at the distance of the Moon) is much larger than the diameter of the Moon.No - the Earth's shadow (at the distance of the Moon) is much larger than the diameter of the Moon.No - the Earth's shadow (at the distance of the Moon) is much larger than the diameter of the Moon.
What is the Moon's maximum distance from the sun?
That would be the Earth's distance from the Sun (at aphelion) plus the Earth-Moon distance. The latter is insignificant.
How bright does a star appear from earth?
It depends on its intrinsic brilliance and its distance from the observer
When does the first quarter phase occur?
First Quarter occurs when the moon is at right angles with respect to the Earth and sun. During this phase, the moon has completed one quarter of it's orbit around the Earth and an observer on Earth will see half of the moon illuminated.
How is the distance from the Earth to the Moon?
About a quarter of a million miles.
Is a star's absolute magnitude dependent on its distance from the observer?
Absolute magnitude is based on an observer being at the same distance from any star.Apparent magnitude is based on the brightness of a star from Earth without any atmosphere.
Relationship between stars distance to earth and luminosity?
Generally speaking, the apparent luminosity would be an inverse square relationship, which is to say, if the same star was at twice the distance, a quarter of the light would be reaching the observer. But absolute luminosity can of course vary without regard to distance from Earth - dim stars can be close, or bright stars distant, or vice-versa.
What is the distance form the earth's moon to the sun?
It's about a quarter million miles greater or less than the distance of the earth to the sun. That's because at times the moon is "between" the earth and the sun and is closer to the sun, and at other times the moon is on the "far side" of the earth from the sun. The distance to the sun from earth varies from about 147 million to 152 million kilometers. The moon is from about 363,000 to 405,000 kilometers from the earth. The distance from the earth to the moon isn't much when compared to the distance to our local star.
What is the point were an azimuth originates?
Azimuth is the distance of a celestial object from the observer who is generally somewhere on the Earth's surface
Is it a greater distance from center of earth to the poles or center of earth to the equator?
I'm thinking center to equator
What can be seen from earth's orbit other than the moon?
The moon's phases can be seen from the earth, but not by an observer on the moon. Similarly, the earth's phases can be seen from the moon, but not by an observer on the earth.
What planet is on maximum distance from the earth?
No matter where earth and Neptune are in their orbits about the sun, Neptune will always be the furthest planet from us. The reason is that the distance between Uranus and Neptune is much greater than the distance between the earth and sun.
If an observer on earth measures the altitude of polaris and finds it to be 0 degrees where is the observer?
At the Equator.
What physical law describes the manner in which the intensity of sunlight changes as the observer moves away from the sun?
The Conservation of Energy or power Law. This gives the inverse distance law of Intensity: Intensity on Earth = intensity on sun (radius/sun distance to earth)2 .
