Alright here goes this is just a theory with a question in the theory if the question is true I feel the theory is correct.

First the question: When you look in the night sky and see reflected light off of a plant 100 light years away that light is a 100 years old correct? This 100 year light is carrying the information of that plant? If we had a strong enough telescope you would be able to see the plant has it was 100 years ago? I guess the question is more of telescopes if I understand correctly that a telescope magnifies the light? So with this stated if we were able to travel faster than the speed of light, the further you went away from Earth the further back in time you could see?

It’s not a practical application just an idea, any thoughts?

I am a Chinese living in my country. I love animals and really want to know more about them, do you think some of the American zoos can accept me as a volunteer? it looks like all the application forms are for Americans, should i stop wasting my time? does it mean that it is impossible for foreigners doing volunteer work in the US? Thank you very much!

Differentiate the following function. y=5e^x+2...

i thought it would be e^x since the 2 becomes zero and the five i thought went away but thats not right.

A reaction is carried out under an atmosphere of oxygen. As the reaction proceeds, oxygen is
consumed. The reaction started in a 500.0 mL flask under a pressure of 1.34 atm and a
temperature of 22.0 °C. How many moles of oxygen had been consumed if at the end of the
reaction the pressure was 1.04 atm and the temperature did not change?

Craters on the moon
Rings around Saturn
and stars.

I don't know much about Astronomy...except a 100 level course. I live in the city and saw Venus in the east, even with 8X25 binoculars could not see m uch.

I looked at Costco website and they range from $69-275 (the most I want to pay is $300.)

What should I look for...or is money spent in this range a waste because quality would be terrible?

I would like to know if the FDA allows a certain amount of moth larvae in food. I have been told this. I recently had a disgusting experience buying a bar and finding it absolutely infested with moth larvae. It has continued to produce further moths and larvae for over a month.

NASA claims on their web site the Space Shuttle is the most complex machine ever built by man

Will you be sad to see it retire in 2010 or do you think the worlds first space plane was a waist of money due to the amount of maintenance it requires between launches plus the two memorable trajeties which received worldwide headlines.

I know he put it in an awful way especially because he seemed to pick on Africans but I do agree somewhat.
My opinion:
- If mean IQ was taken of cultures it would show a difference with race.
- This may be because IQ shows what western society deems inteligent and this would lead to an inherent flaw.
- I think Asians (Japanese would come top, with or cloesly flanked by other Orientals).

His comment was along the lines of, our policies are based on the fact all races are equally inteligent when tests show this is not true.
He then went on to make a few other comments like this is evident in black employees which I think is a bit too far, 'though I'm not old enough to have employees.

Compound A decomposes according to the equation below.

A(g) <~> 2 B(g) + C(g)


A sealed 1.00 L reaction vessel initially contains 1.77 10-3 mol A(g), 1.26 10-3 mol B(g), and 6.09 10-4 mol C(g) at 100°C . When equilibrium is reached, the concentration of A(g) is 2.15 10-3 M. What are the equilibrium concentrations of B(g) and C(g)?

B(g) ____ M

C(g) ____ M
