Hello. Here is a circuit layout based on the ideas of Edwin Gray and Stefan Hartmann. We all know that when a difference of potential is set along a circuit, the charges goes from one terminal to the other, and finally deplete the source. Now, I explain briefly how the proposed circuit...

The arithmetic mean of a set of nine different positive integers is 123456789. Each number in the set contains a different number of digits with the greatest value being a nine-digit number. Find the value of each of the nine numbers .

if a^k =1 and a \in \mathbb{C} k \in Z^+ and for some k A = \{a|a^k = 1\} does |A| = k ? edited: becasue the real numbers are a subset of the complex numbers

I know that as things "fall" towards each other, they lose potential energy, that's fine. What I want to know is when a photon falls towards a mass does the photon also lose potential energy? I would assume so because potons have an equivalent mass. From the equation E = hf, can I therefore...

Let's say that I rig up a truck to a giant helium balloon, but I load up the back of the truck with enough stones so that the truck has reached a state of neutral buoyancy--its just floating in mid-air, not rising not falling, just there. Now let's say I take away a one-pound rock from the...

Over in the Skepticism and Debunking forum, good ole John has suffered several rounds of debunking. If we assume that we have correctly debunked Mr. Edwards, and not to say that all persons would agree that we have, I still have to wonder: Is he really doing more harm than good? If millions of...

I've been thinking... i've always been interested in sex, since i was really young, its almost unbelievable. i always thought it was just a fasination... but now, i think its more just a part of my nature. the other day i was hacking, and soon as topics turned to sex, i was like, awesome. I'm...

Hi I am in a spot of bother. Actually I live in an under developed country where science and technology is not upto the modern standards and there is very little practical facilities. I want to ask if I have a metal sheet of some thickness how it could be made permenantly positive and...

I'm trying to prove that my daughter is my daughter. We just did DNA testing, but either me or my daughter has a mutation in our DNA and the lab is having a hard time coming up with an answer. They said that they are 98.75% sure that I'mno the father, but they won't say I'm the father unless...

I've been doing this question, but can't seem to get past a particular bit. here's the question: 'Two positive point charges Q are held on the x-axis at x = a and at x = -a. A third positive point charge q, of mass m, is placed on the x-axis away from the origin at coordinate x such that |x|...

Why is it that black colors create a positive elctrical charge, while white colors send a negative charge? Does it have to do with different wave lengths? When light (in a copy machine) is focused on to the photoconductive drum, why and how does the black color become positively charged? I...

If matter is positive energy,and spacetime is charged with positive energy from the matters energy that collapsed into a black hole,gravity would attract energy from spacetime.matter could use this energy to produce electromagnetic field.this would also mean that gravity is not a force that acts...
