A. They are in the elements of the circuit
B. They all come from the battery where they were stored
C. They are created in the battery
D. They are created in the wires by the battery


I thought electrons were just stored in wires. I have no idea. I think its either C or D, any help would be greatly appreciated

Oliver has a mass of 76.2 kg. He is riding in an elevator that has a downward acceleration of 1.37 m/s^2.

With what magnitude force does the elevator floor push upward on Oliver?

Imagine that you are in the vacuum of Space. You observe a particle passing you at near to the speed of light (C).
You then observe another one passing you also at near C, but travelling in the opposite direction.
If both occurrences just happened to happen at the same time, there would be a collision; right.

1) Newton would calculate the closing velocity to be the sum of both speeds; in this case almost 2xC

2) Einstein would say 1xC (as nothing can travel faster than C)and so the Newtonian answer must be wrong.

Therefore the nagging Q is: -
Wouldn't the two particles have to "Know" that a light-speed collision is about to occur so that they can slow down sufficiently to satisfy Einstein?

I have a project on Physics which is either make a telescope or a microscope. Does anyone know any site where they tell you how to? We can do reports on it. I hate doing reports. One reason is cause I am not the 'CREATIVE' person. Or we can do a poem. So if you guys know a weird, wacky, FUNNY poem on either telescopes or microscopes, PLEASE do be co-operative. I promise the finder or giver of the best answer, 10 points! ♥

I think it is possible, given the near-perfect vacuum of space. I think space engineers should start by trying to fire a golfball-sized probe towards Proxima Centauri, at about 99% of the speed of light. Maybe it'll take a century or two before engineers are able to achieve this sort of speed. Near-light-speed travel is very interesting and inviting because the crew wouldn't age (much) during the journey. Non-physicists sometimes make statements like, "even at the speed of light, it would take 4 years to reach Alpha Centauri," but, in fact, this is completely wrong. The journey time can be as short as you like, given a speed near enough to 299792.458 km per second. (Light takes about a twentieth of a second to cross the diameter of Earth. The Voyager 1 spacecraft would take 13 minutes. A craft ten times faster than Voyager would take about 1 minute. A craft ten times faster than this would take about 8 seconds. A craft ten times faster than this...)

I've heard of so-called gravitons, the imaginary particles that make gravity happen.
I've also heard of other particles that explain different conditions of weather.

But lately I've wondered if there is a particle that generates warmth... if there is please discribe it and tell me if it's imaginary like the graviton...

Seriously, what books have been published pertinent to ultra contemporary physics after such as Brian Greene's The Elegant Universe(1999) and Fabric of the Universe(2004)? Would someone post some recommended reading lists? Thanks in advance.

The Earth is far too big and heavy for us humans to control its temperature. Similarly, we can't control Earth's flight through space. What do you think?

I thought that there was no notion or physical law of time then nothing would be different, if time never enters the equation then the universe would still operate in exactly the same way it does now. Is this wrogn?
