With all the people screaming about global warming, and how we are responsible, I would like to know who really is correct? It seems that our Weather Experts can't predict next weeks weather, why should I believe them about what will happen next year? If a volcano puts more damaging gases into the ozone layer than we have since walking upright, why does everyone run scared when an activist screams rising tides, world wide flooding?
With 50%+ of the polar ice-cap melted off, why have the tides remained the same as years past?

In Evolutionary theory, I am assuming similarity does not necessarily imply relationship. That would be to retarded to be believed by intelligent humans. Obviously a bat is not considered a transition species between birds and mammals. SO how in fossils do they know what is a transition species and what just acquired similar traits then dead ended. I'm thinking about archeopteryx in particular. How is it known it was an acestor to birds and not just a reptile that developed bird like flight, then dead ended, and birds came from another source.

Please no answers defending evolution. YOu are wasting your time, because I'm not attacking it. Just explain the answers nicely with terms someone with little science background can understand.

I think these things in the shower after talking with friends who are knowers, I have never attended secular education beyond English classes and math, so too many terms will lose me.

Water is draining at the rate of 48pi ft^3/ minute from a conical tank whose diameter at its base is 40 ft and whose height is 60 ft.

a) find an expression for the volume of water in the tank in terms of its radius
b) at what rate is the radius of the water in the tank shrinking when the radius is 16ft?
c) how fast is the height of the water in the tank dropping at the instant that the radius is 16ft?

Do any experts factor in all the animals who eat fiber and covert it into fat, sugar and protein, past and present. Why is it just cows in the present? Cows do not just eat corn from the cob they eat fiborous plants with little food value and convert it with the aid of the flora and fauna in thier stomachs into products like milk and meat. I would guess the Mega fauna of the past were much better at belching and farting than at present. I would also guess that there were bigger herds than in all the feed lots in all the world now. As a side note do deer farts and wild sheep farts count, they do the same thing as cows?

the acceleration of a particle moving along the x-axis at time t is given by a(t)=4t-12. If the velocity is 10 when t=0and the position is 4 when t=0, then the particle is changing direction at???

the choices are:
a) t=1
b) t=3
c) t=5
d) t=1 and t=5
e) t=1 and t=3 and t=5

Why are they all called dinosaurs? I mean it looks to me like there is no moare a relationship between a triceritops and a dynoninchus then thate is between a hippo and a chicken. And how do we know they were all reptiles? Couldn't triceritops be a mammal. He looks like a rhino.

some matter has to escape this cycle it all just cant come back together to form another big bang even if it was one atom at a time over millinia, like the galaxies on the outer edges of universe they have to lose some of there energy and matter to the vastness of space

Can someone explain to me why this is the order of increasing boiling points. I also don't get why glycerine and KBr have the same boiling points.
0.030 m phenol (C6H5OH) < 0.040 m glycerine = 0.020 m KBr


Adrenaline is the hormone that triggeres release of extra glucose molecules in times of stress or emergency. A solution of 0.64 g of adrenaline in 36.0 g of CCl4 causes an elevation of 0.49 C in the boiling point. What is the molar mass of adrenaline?

Can someone help me check if the answer is correct.
For this question I got 182 g/mol.
I found the molality = (0.49)/(5.02) = 0.0976 m
I found the mole = (0.0360)(0.0976) = 0.00351 mol
I found molar mass = (0.64)/(0.00351) = 182 g/mol

and when you go through a black hole you appear in either the "universe" that is larger or smaller than the one you are in now. For example, our universe is inside one molecule in the thumbnail of a very large universe. Also, in my thumbnail there is many many tiny "universes" inside me on a miniscule level.

Sorry if this is confusing. I smoked alot of p** in college.

I know that it involves the body seeing itself, in a way. I know that there are three constituents to the sense of having a body which is one's own: vision, balance organs (vestibular system), and proprioception. I am just trying to put this whole concept together...

Degaussing coils are used to correct color issues on television sets (and other types of video monitors). Many computer monitors have a degauss button built-in, many televisions do not. The coil creates a powerful magnetic field. This field can erase floppy disks, cassettes, etc. What about RFID chips (such as the type forced upon US passport holders starting next year)?
