these teeth are so cool especially the ones that are like 6 inches and i found some for like a couple hundred to a thousand dolars and i also found some on ebay for like ten dollars that were big so i was wondering what is a good price for these because i dont want to be a sucker and fall for the first website i see that charges 3000 dollars when i could have gotten virtually the same thing but for like 200 or something like that so i was wondering where i can get the cheapest but still quality and whole megalodon teeth at because i think it would be awesome to have one of those beautiful things sharks are like the coolest animals in the world to me exept lions. thank you in advance for your helps.

Scientific Rule - Matter can not be created or destroyed
Scientific Theory - Black Holes are a singularity the genarate a HUGE amount of gravity, created by a star.
Scientific Theory - Big Bang; a spinning singulaity that blew all matter out in all directions.
How does the laws of physics not apply to the Big Bang, How? Why? did the Big Bang get started? ???????? This doesn't make any sense.
Are the scientists wrong?
Where's the explanation?
Huh!?

I know it's possible to buy books which give us the names of the various star constellations. 'The Plough', 'The Great Dipper' etc. But there is nothing obvious that makes these individual stars join together in such constellations. How did these stars come to be known by such names ? Who and when was this decided ? And are the constellations different in shape or even in their arrangements to, say, those of the ancient Chinese, or the ancient Egyptians ? If not, how could such arrangements have been universally accepted ?

I was reading the idea that the universe is finite without boudnaries and expanding onto itself


but if I could HYPOTHETICALLY fly to the edge of the universe

( I'm not sure the exact shape -- I'll assume it's a sphere)

so X light years radius I drive from the center ...to the point where it's expanding at that INSTANT ...what would I see? Could I touch it ...would it not allow me to get and further out
..is it like a brick wall

If It were like a sphere....then there has to be something outside that sphere....outside of space and time ...any ideas?

if you suspend a few things and submit that the craft could even exist, go that fast, and stay in tact with you in tact as well,

what would theoretically happen?

In my high school the 4th year science is your desicion to pick. It's either:

Aquatic Science
Anatomy
Physics
or
Pyscholgy(This is considered a social studies class, but i only have room for one of the classes listed above.)

I want to take Honors or AP anatomy, but would the others show better for colleges? I'm intrested in going to Baylor College of Medicine, in Houston.

Thank you :)

An electric dipole consists of charges +2e and -2e separated by 0.78 nm. It is in an electric field of strength 3.4 x 10^6 N/C. Calculate the magnitude of the torque on the dipole when the dipole moment is
(a) parallel to
(b) perpendicular to
(c) antiparallel to the electric field.
What is the difference between potential energies for dipole orientations parallel and antiparallel to the electric field?

Ok so what does this phrase mean? "Every odd whole number can be written as the difference of two squares." And is this a true statement or a false one. If it is false explain to me why, but explain it as if u were talking to a 5th grader....Yeah I'm that bad at math.....

Does the recent discovery of blood cells and tissue on the bone of a t-rex by scientist from the hall creek institute at montana proove to everyone that the t-rex isn't millions of years old

i mean yes it could be very old

but come on, blood cells and tissue on a bone thats over 70 million years old,

i think this just gies to show even when the evidence is staring at people in the face, they still want to hold onto a theory that the evdience does not support

i mean if you found blood cells and tissue onb a dinosaur bone, the most logical thing to conclude is that its not even up to a million years old

blood cells last that long do they?

we are all educated people, we all studied evolution, and this um somewhat contradicts it

Perform the indicated operations and simplify:

(2y)2 (2y3)


x2 + 13x +40 = 0


3x3 – 588x = 0


x2 + 2x = 63


49p2 – 112p + 64 = 0

Factor this trinomial completely: 21y2 + y – 2



THANKS FOR ALL THE HELP!!!!!
