Just a question that popped in my exam... Happened to be only I missed:

The sum of the potential and kinetic energies of a system is said to be conserved when

A) Only when the resultant force acting on the system is zero
B) Only when it moves in a closed cycle
C) Only when the work done by the resultant external force is zero
D) Always
E) None of the above

(or something like that)

I can't understand why A and C are wrong anyways.

I was looking at this Rotheram Museum exhibited that's being hosted at my school in Sheffield at the moment for the week because it's and exhibit on Islam and I was reading the creation story according to the Quran and it sounded much more believable then that of the Bible seen as the Bible says that God made the Earth out of nothing and the skys and everything out of nothing which Science goes against happening whereas the Quran says Heaven and Earth were once one ball of smoke(gas) and stars and planets began to form and they seperated which if you look at Scientific research you can actually see the stars and planets forming in the clouds of gas which ignite to form planets and stars and it just seems much more believeable then the Bible as what the Quran says you can actually see happening today.

I am a 25 year-old virgin and no girl has ever liked me. Whenever girls see me, they run/drive away from me as fast as possible, and therefore I have zero confidence in myself. Since my face resembles my mother’s, I make her feel bad about herself by telling her how girls react to me and placing the blame on her (and on my father). This has taken its toll on her and I simply don’t care. Over the years, my mother’s mental health has deteriorated. She has been hospitalized several times, talks to herself, has become reclusive, and cries a lot. My father hasn’t let it get to him, though I make sure he knows that it’s partially HIS fault that no girl has or will ever be interested in someone as hideously ugly as me. Now, I am sure a lot of you will say I am being cruel, but you haven’t walked through life with MY face, that I have absolutely NO control over. All these other guys, even guys ten years younger than me, are enjoying what I have been missing out on all my life.

So for years and years now ppl have activated against fur pelts and clothing made largely from animal coats. I dont agree with it either. But iv recently started wondering why society allows the use of leather and other animal products?

Good old "genuine bovine hide" isn’t the only popular non-furry clothing addition out there anymore... crocodile skin, zebra skin, and iv noticed the new thing is to have Eel skin. It looks and feels just like good old pleather, but we still have this yearning to own a piece of a dead animal?

how do u feel about these things?

I am wanting to get my mother a telescope but I don't have that much money. So, I am having to get her one that is $100 or less. So, which one do you think is better?

http://www.amazon.com/dp/B000LJMOX6?smid=ATVPDKIKX0DER&tag=sz-ce-20&linkCode=asn

http://shopping.discovery.com/product-65618.html?tcp=Telescopes-featured-MeadeRB70R


Also, I thought if I didn't get it for her for Christmas then I could get her the one that is about $300. So, what do you think of this one?

http://www.telescope.com/control/product/~category_id=starseeker_freeship/~pcategory=starseeker_freeship/~product_id=09741

If you know of one that is better than any of these three that are $100 or less then let me know. Or, I guess if you can find one that is a really nice one that works really great then it can be $300 or less.

Well, thank you. I really appreciate it. Again, thanks.

if you do, do you realise how big it would have had to be to carry at least 7 of nearly every animal?
Do you realise how many tree's it would have needed?
and how do you think he would have gathered animals from all over the world?

I know most of you realise its just a story so this question is directed to the simpltons who think it was fact!

My grandaughter is 15 years old, and went to put the
garbage out, for her mother, only to be harrassed and
when she did'nt respond to that, she was beaten up by
two girls and their brother, then he also struck her mother
many blows to the head, and the sister went inside and
came out with a knife, after all this! went down, should
this just go away, is this allowed in society or is a case
to be prosecuted to the FULL extent of the law? How will
you approach this, it is violence! does anyone have a penalty
for this, or do they have the right to attack neighbours,who
don't know them. I thought that using or attempting to use a
weapon is a violation of any rights, or do they have the right
to beat up people who mind their own business, because
they have enough sense to know the consequences of
their own actions, is this only for some and not others?
Somehow they're on the street hoping to repeat this!
Where's juvenile justice then! since they are children.

Has anyone else here noticed that questions about JW's seem end up being violations frequently? Even questions that violate absolutely no rules. Yet they are reported and you lose point. Anyone else notice this?

Also anyone else notice that JW's seem to block anyone who answers in a way that they cannot refute?

On a site about Halloween decorations there were links to spooky pictures to print off, one of them was of a civil war era teenage boy with some fingers missing, here's the link http://members.tripod.com/~Motomom/fingerless.jpg

My bf says its obvious that his fingers are inside his jacket but I'm not so sure, cos there's no opening there where he coulda slipped the fingers inside, and also it looks like not only the fingers but part of the hand is missing. What do you think, real or fake?

(The creepy thing is that boy looks alot like my friend's lil brother, who is currently trying to join the army, freaky!)

Why don't Neon lasers or helium lasers exist on their own, and instead they are combined to form He-Ne lasers?

Thanksgiving is now a Day of Mourning? No more Christmas Trees or Reindeer, instead its Penguins and Snowflakes. It seems our American traditions have been under attack for some time even more so, since 9/11.Do you feel that Socialism is getting more of a foothold in America? If so, what should we do?

Really, why don't we make wooden cars. Wouldn't they be cheaper, lighter, spend less gas ect. Of course, we could surround engine with metal and have metal parts, but the body should be made of wood. A lot painting, and it should last a decade. They would be cheaper, so we could change them more often.

What do you think about it?
