    Have a hard question you want an answer to, post it here.

    How much does the planet Earth weigh?

    I was splitting wood the other day and was moving it around. I know that one part of a tree I was moving was at least 300lbs. There are alot of trees on the Earth. That is where I thought of that question.

    You are correct, the problem is impossible as stated. Weight is relative. Or do you mean how much would the Earth weigh if it were accelerated at the same constant 9.8 meters per second squared that we on the planets surface experience? After all even on the surface of the earth, at different positions you weigh different amounts. For example, you weigh less in Denver than you do in Miami.

    With objects not effectively stuck to a certain planet it is much better to talk about mass rather than weight. The mass of the Earth, according to the JPL, is approxiametely 5.9736*10^24 kg, which according to the assumption we made earlier translates to approxiametely 1.3172*10^25 lb.

    Hope that helps or barring actual aid merely deepens your confusion.

    So basically it is alot. :)

    I was going on the assumption if it was possible to take the Earth and put it on a scale, what would the weight be.

    What is JPL?

    JPL is Jet Propulsion Labs.

    Again where would the position of the scale be. The weight of the Earth is relative to where the measurement is being taken. The number above is based on the assumption that the scale is on Earth, hence the 9.8 meters per second squared acceleration. So now for a list of the weight of the Earth at different positions in the Solar system:

    Sun: 3.6882*10^26
    Mercury: 5.0054*10^24 lb
    Venus: 1.1987*10^25 lb
    Earth: 1.3172*10^25 lb
    Mars: 5.0054*10^24 lb
    Jupiter: 3.3457*10^25 lb
    Saturn:1.2250*10^25 lb
    Uranus: 1.0538*10^25 lb
    Neptune: 1.5806*10^25 lb
    Puto-Charon: 5.2688*10^23 lb

    Jet Propulsion Labs is a division of NASA. They do most of the analyzing of data

    You have to much time on your hands Emp, either that or you read to much.

    One in the same, I think.

    So, to make the question probable and logical...How much would the Earth weigh if put on a planet that was completely a perfect sphere of iron one hundred times the size of the Earth and free from the pull of any other gravitational disturbances or friction?

    100 times the volume or diameter of the Earth? The answer is different for either.

    Can you read too much? That is the real impossible question.

    I think that would depend on the person.

    Diameter. The volume would increase at a constant rate as the diameter increased, assuming the substance (iron) was consistant throughout the sphere).

    Women are twice as likely as men to do this in the bathroom. What is it?

    Quite a few things...

    Actually Josh the volume of a sphere increases exponentially in proportion to the size of the sphere's diameter. So it actually increases quite fast. now onto the question. a planet of the size described would have the following statistics:
    Diameter: 1275628 km
    Volume: 1.08685*10^18 Cubic kilometers.
    Mass: 6.69746*10^20 kg

    Weight of the Earth on this planet:
    In Newtons: 6.56265*10^23 N
    In Pounds: 1.47475*10^23 lb

    Why did I include the Newton measurement?. Because pounds only have meaning when dealing with terrestial objects. But there is your answer.

    Well, accourding to a study, women are twice as likly to talk on the phone while going to the bathroom then men.

    Now what are men twice as likely to do in the bathroom then women?

    Yes. That what I said. As the diameter increases, the volume would constantly increase as well.

    I really hate it when people begin a sentance with "actually".

    Actually the feelings you have for that are tied to something else deep in you inner self. Would you like to talk about it? :)

    Josh, you saidconstant rate. The volume increases proportionally to the radius cubed. A very large difference.
    So Charles did you verify my numbers yet?

    Knnos has been scarce on the boards for the past few month. He must think his schooling is more important than our post count.

    Sorry gents, education has become the priority, I shall not do it again...

    my Physics teacher flatly refused to answer the question, he said it was ridiculous. It doesn't help that he thinks I'm a bum. Sorry.

    The answer to this question (What are men twice as likely to do in the bathroom then women?) is: Read the newspaper.

    Empyre: ACTUALLY, I said that that the rate would constantly increase, not that the rate of increase would be constant. At least, that's what I meant. :)

    BDZ: That's not the answer I would have guessed.
