What is the brightess planet?
Viewed from Earth, Venus is the brightest planet.
How did carbon reach Earth?
All elements heavier than hydrogen, including carbon, were produced by fusion in the centre of stars, which then exploded (supernova), and the debris was part of the Earth's formation.
What is the astronaut's weight on the moon?
If something weighs 127kg on Earth it will weigh 21kg on the Moon.
Where on the earth would the weight of body be zero why?
on the centre of the earth.
Why is the weight of a body zero at the center of the earth?
At the centre of the Earth, or any body for that matter, the mass of the Earth is centralised at the centre, At the centre of the earth there is no weight attributable to the earth's mass. But there is weight (a force) attributable to the sun's mass, neatly balanced out by the speed of the earth in its circular orbit. So the weight is mv2/r instead of mg (m= a mass placed at the centre, v=velocity in orbit, r= distance to sun). If the earth slowed to a stop, it, and everything at its centre would accelerate towards the sun. If somehow you could nail the earth down so it didn't fall in, that weight would be measureable with a spring balance. Ignoring galactic and intergalactic forces. I guess that's sophistry really.

What happens to the weight of an object when it moves farther away from the centre of the earth?
the weight of an object grows more
Does weight act towards the centre of the earth?
Yes, at the center it becomes zero.
What change in weight occurs going towards the centre of the Earth?
Gravity... :D
How weight can change?
As the mass of a body or things is constant , the weight only depends on the the gravity 'g'. As the gravity increases with the decrease of the hight of the mass from the centre of the earth , the mass also increases with the decrease of hight from the centre of the earth.
Why does a body lose weight at the centre of the earth?
In the center of the Earth gravity is equal at every side causing you to be "weightless".
What is the definition of weight as it is used in science and technology?
Weight is the FORCE by which Earth PULL any body towards it centre of gravity.
How is the mass of a pencil different from its weight?
The mass will always stay the same but the gravitational pull towards the centre of the earth (weight) will change.
What would be the gravitational force on you if you were at a point in space a distance R the Earth's radius above the Earth's surface?
one-fourth of your weight on earth
Where does a body have least weight equator or earth centre?
In the middle of the earth is where an object has the lightest weight. The weight is zero. The reason is that the mass of the object is pulled equally in all directions so all the forces cancel out.
