You haven't said 'half' of WHAT .
I'll assume that you mean "half of what it is on the surface", and
I shall now proceed to answer the question that I have invented:
(x/earth radius)2 = 2
x = (earth radius) times sqrt(2) =
- 9,010 km (5,599 miles) from the center
- 2,639 km (1,640 miles) from the surface

What eclipse can be seen by about half of the earth at once?
That is a lunar eclipse which can be seen from everywhere on the dark side of the Earth, which is always a hemisphere with its centre at the place where the Sun is directly downwards.
If the moon were twice as far from the earth as it is now the gravitational force it exert on the earth would be?
half its present value
How does the planets distance from the sun affect its conditions?
The farther away from the sun the planet is, the more space it has to cover. Therefore, the planets distance from the sun whereas, if i am half the distance from Earth/Sun, that planet will get more energy. But if I am twice the distance from Earth/Sun, I will receive less energy.
How high does a rocket have to go above Earth's surface until its weight is half what it would be on Earth?
Gravitational pull provides weight to each object. This pull is from the center of the earth which is 6378 km from the surface. To decrease your weight by half, one needs to travel another 2641.9 km from the surface.
What planet has the force of gravity here that has less than half of the pull exerted by gravity on earth?
I'm not sure if it's half or not, probably less, but the only possibility would be Mercury. True. Mercury is the only one. Gravity on Mercury's surface is 37% of what it is on Earth. Except for Mars, where it's 38% of its value on Earth. Mercury and Mars are the only ones. Except for Pluto, where it's 4% of its value on Earth.
What height from the centre of earth the value of g is half of its value on the surface of earth?
gravity follows an inverse squared law. at twice the distance it would be a quarter of G. 1/g2 = 1/2. so the distance would be the square root of 2 (or 1.4). 1.4 x earths radius of 6366 km would be 9003 km
Why is the radius of the circle half the diameter?
The radius of a circle is the distance from the centre to the rim. The diameter is the distance fron rim to rim passing through the centre point. It therefore follows that the radius is half the diameter
How does one calculate the space to mounting height ratio for lighting?
Half the distance from the wall to the centre of the luminaire, as the distance there is between luminaires. e.g if the distance between luminaires horizontally is 3m then the distance to the centre of the luminaire from the wall is 1.5m. If the distance between the luminaires vertically is 5m then the distance to the centre of the luminaire from the wall is 2.5m
What is radius equal to?
Radius is half of the diameter - i.e. it is the distance from the centre to the edge of the circle.
What is the radius of a circle with a 3cm diameter?
The radius would be HALF the diameter, making the answer 1.5cm ! The diameter of a circle is the distance across it, passing through the centre. The radius is the distance from the centre to the edge.
What is the distance between Melbourne and Geelong?
Geelong is roughly an hour and a half drive from the city centre of Melbourne. The distance is approx 75 Kilometres.
How do you figuer out the radius of a circle?
The radius is the distance from the centre of the circle to the edge, the radius is half of the diameter. I hope this helps
What is the distance of the habitable zone from a red dwarf star?
About 0.5 AU, or about half the distance from Earth to the sun.
How far is it from north to south?
About 12,500 miles which is half the distance around the earth.
What is the furthest distance from north to south?
The furthest distance from north to south (on the earth) would be the distance from the north pole to the south pole, or half of the earth's polar circumference. It's about 12,400 miles, just a little bit less than half-way around the equator.
How far is it from north to south poles?
About 12,500 miles which is half the distance around the earth.
What eclipse can be seen by about half of the earth at once?
That is a lunar eclipse which can be seen from everywhere on the dark side of the Earth, which is always a hemisphere with its centre at the place where the Sun is directly downwards.
