If the center of gravity is kept at the same place; the footprint of solid tires is equal and at the same distance, What are the effects of angling the shafts as in this setting, instead of / compared to the 'normal' horizontal shaft Why if the answer is stability ?

Hello friends I just thinking about the wireless electricity transmission, if any body can help me about that, then i can fit a small dish antena in the top of my car and drive Billy

can we store static electricity in any form like with the help of rechargeable batteries, if possible pl let me know how?

I have tried as hard as I am able to get a grasp on the complex laws of physics that define our universe, though I'm sure my knowledge of the subject is actually quite minuscule. I have been wanting to begin work on a sci-fi novel, however I'm determined to think of my own unique (at least relatively) form of FTL travel before I do. I have theorized that light's speed limit could be set by ever present cold dark matter, it seems this could be plausible as i recall reading somewhere that light travels slightly faster in some parts of the universe than in others (where there could be an unusually low amount of cold dark matter.) I don't want to get too attached to this the…

How can we relate nano technology with physics ?

Why only water is used in water in boilers at steam power plant? can we use other liquid? water has high boiling point and latent heat of vaporization so it requires more energy to make steam from it, what if we use some other liquid having lower latent heat of vaporization and use its vapours for same purpose as steam , can we save energy which is wasting in conversion of water to steam?

Is there any advantage to spinning (accelerating) perimeter cross blades as illustrated here: http://elanetics.com/turbinearray.html by their tips (by the magnetic coupling of center blades) as opposed to spinning them individually from the center with a generator/motor. Same energy required for both methods? Need to know if this unique coupling plus unique magnetic involute gear configuratioin is worth anything. Any comments would be greatly appreciated. Don

I was wondering about the bulk of the volume of an atom. If electrons stopped moving (whether particle or wave function) in the atoms of your body you would be the slightest layer of dust on the floor. If you were in a hermetically sealed container only just big enough to contain you and this hypothetical event happened would the container contain almost a vacuum or would it be full of air? Are you a walking vacuum or a walking bag of air?

As you look at galaxies further and further away, they appear to be moving faster and faster away from us, doesn't it also mean that galaxies that we see more in a past are moving away faster then the ones we see closest to the present time. Why cant we then conclude the obvious from it, that the Universe is slowing down in expansion. I have learn't about Universe actually increasing its speed of expansion. But isn't the true answer obvious from a fact I have just mentioned, and that they must have made an error in measurement.

So, the question I have is: "How does a charged particle rotating around it's central axis and moving with a constant velocity (v) behave when it enters a magnetic field?" I know the right hand rules and I know how it behaves when it only moves forward with the velocity v. But what happens when she's both doing rotational and translational motion? How does her path look then? And what happens with its velocity and the force acting upon it? (Drawings would be much appreciated.)

Hi guys this is my first official post. I have been watching the TBS comedy The Big Bang Theory and ever since I started watching it, I have had an increased interest in learning physics and the other science fields portrayed in the show. One of the biggest things I want to learn are the concepts of what Sheldon Cooper is studying. What exactly is it that he is studying and are there any websites out there that give a simple explanation of some of those things? I'm a huge education lover and I'll soak up anything I can. If anybody has any good advice to give me on learning the things that they talk about on TBBT, please let me know!

So I was bored for a bit at work today & decided to do a little math. I will admit, I trusted KGB to give me the average volume of a human body, which was off by 10 to the -15th. Then, when I 'corrected' their math, I was off my 10 to the -1th, so this is the revamped version. I hope it is all relatively accurate now. Measurable Theoretical Breakdown ofthe Universe: A Paper for Amusement by Pete Lerza 11/10/2012 I’ve done all mathematics with fairlyloose approximations. The purpose of this is not for scientific accuracy, butfor a general understanding of a theoretical size of the Universe. The Names ofthe Large Numbers are in the American…

hey yall im currently in a dialogue and im wondering if the person is right he says: On our physical plane of existence we can detect only about 100 octaves of electromagnetic radiation, ranging from radio waves through visible light to x-rays and gamma rays, the electromagnetic spectrum covers an infinite range of frequencies – or at least we have no reason to believe otherwise. What to us is 'empty' space is simply those regions of space containing no grade of matter that is perceptible to our physical senses. An important property of electromagnetic energy is that waves of sufficiently different frequencies do not interfere or interact. If phy…

Sorry for my stupidity (as I'm in my young days of learning) but is was wondering about what happens to photons when you turn off a light since photons is light.

I'm wondering about the energy/flow of water in a pipe. The continuity equation states that u1A1=u2A2. Say for instance, a turbine is placed in the pipe to extract energy from the flow; by the conservation of mass, neither the cross-sectional area or the velocity of the flow can change if the pipe diameter is constant both upstream and downstream of the turbine. However, surely the turbine must extract energy from the flow, such that it has less energy on the downstream side? How is this reflected in the flow, when the volumetric flow is unchanged?

I would like to know the laws that can not be deduced from others, I know that they are many, but citing at least one is better than nothing.

Hi, all I'm in polymer science and trying to use molecular dynamics simulation (MD) to study the aggregation behaviour of electrically neutral nano-particles in polymer melts. The short-range interaction of two neighbouring particles are represented by a Lennard-Jones potential function. Presume the two neighbouring particles are immersed in some uniform matrix with different dielectric constant, how does the interaction change with the dielectric constant of the matrix? Is it related to the depth of the potential well of potential function? Any suggestion is highly appreciated.

I've been pondering over this in my head for days now, and still can't decide upon what is the correct assumption. If you were to hold a horseshoe magnet over a magnetic material (let's say iron) with both poles facing down, and the slowly turn it clockwise, would the poles of the iron molecules (excuse my leyman terms) eventually come to align in a circle in the direction of movement, or would they constantly reverse as the next pole passes over them? Please put my mind at rest. Thank you in advance for your answers.

I know that it's because of their different atomic structure, but why? I think I have an idea of why specific properties are present in some elements, like radioactivity(because of their instability) or reactivity with other elements(because of their electron configuration) or atomic weight (because of the number of protons and neutrons)...etc. But how do any of those(or something else I'm most likely unaware of) explain color, texture, melting points and boiling points, density, and many other properties I can't think of at the moment(what are the other properties?). Like, why is gold's color different than silver? I don't know much about science, besides a fe…

i have heard of something called the particle wave duality. Now energy shouldn't technically be classified as a particle. Energy is what we get as a bi-product of mass being converted. So, in my opinion, if what people call the particle wave duality exists, then the smallest particle i could think of should be light. Oh well, this isn't my area, but its my true opinion

Should physicists formulate a theory of everything? would you agree with formulating such a theory or would u prevent it from being formulated?

If water has to go into the sky to make rain, why does it go down? Why does it take the time to go all the way through the earth and in China's sky, when it could just go up? Is it racism against America?

This video shows how the double slit experiment is affected simply by observation. Is this true? Does simply observing the experiment show that reality is affected by the mind or does it show something else. 2:45 long video

Hi everyone! Firstly, let me say hi to everyone! I hope to participate as much as I can - both asking and answering questions when need be. I'm sure I'll enjoy it - this looks to be a pretty good forum! Now onto my first question. I have very little understanding about fluid and 'gas' mechanics, however I'd like some help when it comes to thinking about a certain instrument - the bagpipes. I've played them for about nine years now, and throughout that time, there has been quiet a 'debate' over wether or not the material of the bag affects the tone of the bagpipe. Please understand that 'proper' playing of the bagpipes results in a nice smooth tone - not a ba…

ICBMs How can long range nuclear capable Inter Continental ballistic Missiles be upgraded and improved to destroy very large meteors and asteroids high up in atmosphere at approx. 40-50 miles so as to cause minimum damage to population??
