The average centre-to-centre distance from the Earth to the Moon is 384,403 km, about thirty times the diameter of the Earth. 1km=1000m so 384,403,000m. Or it's 238,857miles
Yes, it does, and it is moving away slightly from each other. The moon moves away a few inches a year. Probably four inches.

Distance from earth to the moon in light years?
Mean Distance from Earth: 3.844x10^8 m Speed of Light (in a vaccum) 3x10^8 m/s T = D/V T = 3.844x10^8 m / 3x10^8 m/s T ~= 1.28 seconds Pleae note that the moon/earth distance varies, thus we used the mean in this equation.
The distance from Earth to the moon is about 3.8 x 108 m A beam of light is sent to the moon and after it reflects returns to Earth How long did it take to make the round trip?
My almanac lists the average distance from earth to moon as 384,401 km. Round trip = 768,802 km. Time = (distance) divided by (speed) = (768,802,000) / (3.8 x 108) = (7.68802 x 108) / (3.8 x 108) = 2.563 seconds (rounded)
Why is the acceleration on the moon less than on earth?
There exists a universal law of gravitation discovered by Newton which governs the force between any two masses. The size of the force is in proportion to the product of the masses divided by the square of the distance between the centres of the masses. Take an apple mass m at a distance R from the centre of the Earth mass M. The force (gravitational force aka weight) is proportional to (m x M)/R2. On the Moon mass N radius S, the force is proportional to (m x N)/S2. Because the Moon is much less massive than the Earth the ratio of these two forces is about 8 to 1 (check this fact) even though S is much smaller than R. The acceleration of a body released under gravity is the force divided by the mass ( a= F/m) : this is F=ma restated and experimental law called Newtons second law and this is a constant irrsspective of the mass of the body- the mass m cancels out because mM/R2 divided by m is proiportional to M/R2. For Earth and Moon the accelerations due to gravity are in proportion of M/R2 to N/S2 and this ratio is about 8 to 1 as I recall.
Consider a pulse of laser light aimed at the Moon that bounces back to Earth The distance between Earth and the Moon is 3.8x108 m Show that the round-trip time for the light is 2.5 s?
The speed of light is roughly 3.0x10^5 km/s, while the distance for a round trip is roughly 7.6x10^5 km. The time can be found by dividing the distance by the speed, which results in 2.5 seconds when obeying standard significant figures rules.
Why does the sun not attract the moon?
Well, I'll start with some Physics, which is going to be the basis of the answer. The formula F=ma (learn it if you don't know it), means effectively that the mass of the body in the relationship, the greater the force (as 'm' (mass) increases, if 'a' (acceleration) is some constant (other than 0), then as m increases, so does F (Force)). It logically follows that the force of gravity between the Sun and the Earth will be greater than between the Sun and the Moon. Since the Moon is so small, the force is actually relatively insignificant, which means that the Moon is significantly more attracted to the Earth, which is closer.The Sun does attract the Moon, but not significantly enough to make the Moon leave the orbit of the Earth. It orbits the Earth because the pull of the Earth is greater as the distance is smaller. For a greater understanding of the subject, you may want to check out Centripetal Force.

What is the distance between the EHV lines and earth?
14 m
What planet's distance from the sun is about 72 percent of the distance from the sun to the earth?
The distance between the Sun and the Earth is 1 AU (149.597 m km / 93 m miles) whereas the distance between the Sun and Venus is at an average of 0.723 AU (108. 200 m km / 67.625 m miles). So it can be called 72% of the Sun-Earth distance.
Distance Earth to Moon?
Because the moon's orbit is an ellipse it depends on what time you're talking about and where you are on the earth due to different altitudes; which can get very complicated. But the average distance is 3.84*10^8 m.
What is measured using a appropriate for the distance between two points?
In scientific measurements, however, length is the distance between two points. That distance might be the diameter of a hair or the distance from earth to the moon. The SI base unit of length is the meter, m. A baseball bat is about 1 m long. Metric rulers and meter-sticks are used to measure length. FIGURE 12 compares a meter and a yard.
Does a solar eclipse occur when earth falls between the sun and the moon?
No. This planetary alignment causes a lunar eclipse because, the earth blocks the sun's rays from reaching the moon, so that the moon is inside the earth's shadow. S<<<E===m in the diagram above s represents the sun E represtents the Earth and m represents the moon. The< represents the sun's rays and the = represents the Earth's shadow.

How far does the moon move away from the earth each year why?
As a result of the conservation of angular momentum, the slowing of Earth's rotation is accompanied by an increase of the mean Earth-Moon distance of about 3.8 m per century, or 3.8 cm per year.
What the difference between the acceleration of a baseball one earth compared to the moon?
A baseball on Earth will accelerate towards the center at 9.8 m/s^2 A baseball on the Moon will accelerate towards the center at 1.63 m/s^2 (according to wiki)
If your mass on earth is m your mass at a distance of 3 earth radii from the center of the earth will be while your weight will be?
-- If your mass is 'm', then your mass is 'm', regardless of whether you're on the earth,2 earth radii out in space, or on the moon. Mass doesn't change.-- On the surface, your distance from the center of the earth is 1 earth radius. Weight isinversely proportional to the square of the distance from the center of the earth, so at adistance of 3 earth radii from the center, your weight is 1/32 = 1/9th of your weight on thesurface. If your mass is 'm' then your weight on the surface is mg = 9.8m newtons, and at3 earth radii from the center it's 1.089m newtons (rounded).
