TEST YOUR EARTH'S KNOWLEDGE

Post by Guest »

Good evening my friends.

I'll be posting some trivial questions here to test your knowledge but just for fun, no competition no bad spamming allowed.

Have fun...I hope.

Earth's weight is estimated to be six trillion tons.

Question : What would be the Earth's weight if one trillion tons of cement was used to build a wall?

Not my own question.

The same because the weight would already be there from the materials used so little or no change in weight.

Hello Scourge,Bdw3

You should have let the others figure it out before.
I knew you would have find it right away.

In the meantime, just for your pleasure.

The earth weight is estimated at six trillion tons.
6,000,000,000,000 tons US
Or 12,000,000,000,000,000 pounds
Or 6,000,000,000,000,000,000 tons European and other countries.
Or 12,000,000,000,000,000,000,000 pounds
World population is estimated to be 6.5 billion (mid-2005) and growing by 76 million a year. That's about 200,000 people each day. In other words, a population larger than that of the UK is being added to the planet each year - one city every single day. The environmental consequences are already clear - the planet can't take it.

And as for … Re: if EVERYONE in the world went to the north pole

would the world move?
…question…

If we are 6.5 billion people…
6,500,000,000 X 120pounds(average person weight) = 780,000,000.000 pounds
Earth =12,000,000,000,000,000 pounds

.000065 15,384.6 contre un
Like one person against 15,384.6X120=1,846,152pounds.

pete, don't take this the wrong way, but that problem was like something you'd see in a grade school level book of problem solving practice - so don't be too hard on the guys who solved it 'first'.

that's a lot of air bubbles trapped in cement.

i think air has mass ? airborne particles would be in the wall ..even extra- terrestrial
matter.

so i say the earth would weigh more with the wall

Air is matter, so of course it has mass.
You are overthinking the problem, though, I'd guess.

Check out the brain on this one!

:confused: No Not really, just funny. Nice try.

BTW, Ever tought about Romans with their romans numbers...
They never invent the 0 roman number.

What would they used when: X-X=nothing???

thats ebcause the romans only used the numerals for counting

Roman numerals only work for natural numbers and zero is not a natural number.

Just another fact/comparative to help us visualise the Hotmail
popularity of its members.

Just read that Hotmail is the most used free email messages service cie, with 190M active members worldwide.

What would be the lenght of a human chain, if every Hotmail members were linked hand in hand? ( for the purpose of the calculation, we will use the lenght of a person hand to hand opening 5 1/2 feet.)

Try it if you want, I will post some comparative later.

There is about 6 feet of DNA in each nucleated cell in the human body.

Now, go find out how many cells there are in the body, then figure out about how long all the DNA in a human would be if it was stretched out end to end.

Let me know when you get the number. It's longer than the distance to the Sun (or is it the moon) by quite a bit.

I have my students do shit like this when teaching them dimensional analysis and whatnot.

This year just freshmen and sophomores. I've taught college for a couple years, then taught advanced chemistry to juniors and seniors (and really smart sophomores).

Not my own.

The DNA molecule is a double thread, coiled into a helix. The genetically important constituents of DNA are four nucleotides
The total DNA in a human cell, if the DNA molecules of each chromosome were lined up end to end, would be some 6 feet in length
Each human individual is made up of several hundred million million microscopic cells (plus considerable noncellular material such as bone and water). Cells come in a variety of shapes and sizes.
So TNF do we have to multiply several hundred million million microscopic cells X 6 feet.X 1 or 4 ?

Thanks for your trivial question

Pete, before you explain any more DNA information to me...please remember that I was a molecular biologist...I appreciate the explanation though.

Just take the 6 feet and multiply it by the number of nucleated cells in the body (its an estimate) - remember, muscle cells are multinucleated, red blood cells are enucleated during hematopoeisis, etc.

There are varying estimates as to the number of cells in an adult, but lets use a common estimate of 10 trillion.

So, do the math - about 6 feet/cell x 10 trillion cells = how many miles? Now convert that to astronomical units. People are pretty surprised when they see how much there is. And even more interesting is the fact that each of those 10 trillion cells (with nuclei) have pretty much ALL the instructions for making a whole human. The entire instruction manual for a human is crammed into something as small as a cell nucleus. Talk about compression of information.

Sir tnf, There is some misunderstanding in here, I precised these infos were not my own.

I know from your replies that you aren't ( un deux de pique ).

Is it true that we have like 30 some feet of colons inside?

Tnf, if you can help me again.

I read about that, years ago and it hasn't changed in Google research. About Human Veins ...60,000 to 100,000miles in a single person. So like 3 to 5 times the earth circumference.

Thanks tnf

Pete
