Science is limited...
the best they can come up with is tiny atoms and electrical charges...
carbon!
The universe zoomed out 10 to the 20th power...looks alot like a cell zoomed up to 1 micron...am I onto anything? besides the fact that science is man made.

If evelution is real, then what is the chance that everything just started to exist. WHy hasn't it happened again. If the sun is 10000000 some years old than why hasn't it burnt up yet. If life is that long, how com the "apes" didn't come up with any inventions. Why haven't we morfed, why haven't we seen anything morph, how can all this happen by . It had to have been planned. By who would that be JESUS CHRIST!!!!!!! deal with the fact that he is the creater and that public school teaches BULLLLLL!

A 200 pound box of books on the floor requires a 140 pound horizontal force to make it start sliding on the floor, but only a 50 pound force to keep it sliding at a constant speed. What is the coefficient of static friction between the box and the floor?
Explain answer please

If the sun will eventually run out of fuel and then die can we not in the future feed the sun some hydrogen, perhaps fling a jupiter or something into it to make it last indefinitely

The knot at the junction is in equilibrium under the influence of four forces acting on it. The F force acts from above on the left at an angle of A degrees with the horizontal. The 5.1 N force acts from above on the right at an angle of 49 degrees with the horizontal. The 5.3 N force acts from below on the right at an angle of 42 degrees with the horizontal. The 5.9 N force acts from below on the left at an angle of 45 degrees with the horizontal.
a. What is the magnitude of the force F in Newtons?
b. What is the angle A of the force F?

This is a serious question beyond my ability to fully think through with mathematical rigor and design an experimental proof. I did what I could, and got nowhere. Unfortunately, I could not disprove this idea.

Electrical dipole moments attract each other. Could gravity just be the collective dipole moments of matter? If you sum all the dipole moments in an atom, is the sum of their forces roughly equivalent to the gravitational force of the atom?

I heard some DISTURBING descriptions in the story, "The Cold Equations" by Tom Goodwin. but does anyone know EXACTLY? And also, wouldnt it be ....sort of like drowning? i mean , no air, you suffocate. so why does the nasty stuff w/ your organs happen or whatever? thanks. -Amber

Some time ago a man named Nicholae Tesla realized that the Earth is a huge electrical generator. He said that if humanity could create a copper cable long enough to circumnavigate the earth from South pole to North pole and back, we could use the power generated naturally by the earth's magnetic field and have enough power to light a billion New York-sized cities. I assure you this is true. So my question is really this: Why do you think we haven't we decided to use the most efficient form of renewable energy? At this point in history, we have the technology and engineering ability to achieve it, so what's the hold up?

with a mass of 3.49 kg and a radius of 0.075 m starts from rest at a height of 3.60 m and rolls down a 43.8 degree slope. Acceleration of gravity is 9.81 m/s^2.

What is the translational speed of the cylinder when it leaves the incline in units of m/s?

record that is 12 in in diameter. The record moves from rest to its final angular speed
in 2.91 s.

What is the bug's centripetal acceleration 1.5 s after the bug starts from rest (in m/s^2)?
1 in. = 2.54 cm

Possibly?
ac = v^2/r

I'm trying to figure out how to find the amount of time it takes to cool a boiling pot of water to 180 degrees Fahrenheit, sitting at room temperature. Is there a simple way of doing this?

Its possible for me to find the amount of energy used in going from 212 degrees to 180, but not quite sure where to go from there.

Thanks

I was talking to a friend today he was telling me in 2012 the earths polarity will change. Like North with become South, South become North and the earth will start to rotate in the oppsite direction. I was reading a little bit on Nasa website and it was saying that the sun's polarity was dur to change in 2012. I was just wondering do u think this will happen to earth?
