Effects Definition and 1000 Threads

I've been digging around on the internet for information about magnets. I've found some interesting thing like the inverse square law of intensity, but I've noticed the Lorentz equations tend to deal mostly with charged particles. I'm really looking for information about the net field's...

I had a question that I was hoping someone could answer for me. If light passes next to a massive rotating object such as a black hole, would the affects of frame dragging cause a blue shift or would the light essentialy travel at a speed faster than the C?

I had this lab done where we took beets and tested the effects of pH on membrane permeability. We used different concentrations of HCl and NaOH. Why did I get such a strong colour intensity with a test tube that had 0.001 M NaOH? And how do I know this experiment affected the protein...

What kind of short term and long term effects does DMT have on the brain?

My teacher asked a very interesting question. so given a runge function 1/(1+x^2) and i interpolate it on uniformly spaced point in the inteval -1 and 1 by p_n(x) How does the pole -i and i contribute to the oscillation of p_n(x)? I never thought pole would come into play.

I was recently listening to a favorite podcast of mine (AstronomyCast) and they went over the tidal effects the moon's gravity has on the Earth. I just happened to be thinking about the tidal effects after that and was wondering if the moon's gravity effects things in orbit of Earth. More...

I am just curious, can frequent masterbation have a permanent reduced sperm count side effect in the long run ?

Back in the early days of telegraph and telephone lines, electromagnetic storms emanating from the sun shut down communications services over land lines. As the decades progressed, solar storms no longer affected those lines. What engineering change was made to land lines to insulate them...

Why does the double-slit experiment with a laser work properly in an atmosphere? Likewise, I've seen news reports of entangled photons transmitted in a fiber or in open-air used to generate a shared secret. So, both superposition and entanglement works. But, the fact that the speed of the...

I am starting to program a simple physics model of a car to help me understand how it works. I am certainly going to have to make quite a few simplifications as I'm only just about to start A levels. Whilst researching how to simulate engine braking I came across the Racer (racing simulator)...

I was wondering how the time period of a double pendulum depends on the mass of the intermediate object and its distance from the bob?

Sirtuins are enzymes which repair telemeres that deteriorate to cause aging. They are normally released in response to stress such as calorie restriction or low insulin levels, but sir2 can be stimulated by certain chemicals. Why is it unfeasible to take molecules like resveratrol (found in red...

Which should happen around December 2012 according to NASA. From what I have read this could be the end of the world and a beginning of new.

Hi Does anyone have a link to a proof that magnetism is a result of relativistic effects on a moving charge? I am sure that I have seen one but I can't find it. Thanks John

I'm working on a project that involves putting electronics equipment into a solid metal (aluminum) case. The cases are sealed watertight and I need to be able to transfer the heat originated at the electrical components to the ambient air. I can perform the analysis to get a pretty good idea...

Homework Statement An electron is projected at an angle of 31.7° above the horizontal at a speed of 8.40×10^5 m/s in a region where the electric field is E = 383j N/C. Neglecting the effects of gravity, calculate the time it takes the electron to return to its initial height. Homework...

why does a razor blade placed on the water surface move away from a charged body?

What would be the practical effects if it is proved that P=NP and an efficient polynomial time algorithm is found for NP-complete problems? By practical effects, I mean the practical effects of perfectly solving the problems which have been proven to be NP-complete (like Boolean SAT...

The following diagram is of a setup consisting of A bulb A pair of wires...making an angle theta with the place the bulb lies in now if the setup is seen by an observer moving at a speed 'v' relative the angle the wires make with the plane changes to phi>theta(i can provide the...

hi friends can you help me in collecting systematically some important phenomenon or 'effects' in astronomy and astrophysics like rossiter effect, yarkovsky effect.:cool: even recently discovered phenomenon and related explanations are welcome.:approve:

Ok, i am given this task by my physics group leader and is required to do an experiment based on the following research question: To investigate the effect of temperature to the conductivity of a charcoal rod. i. How do i heat a charcoal rod to a desired temperature and make it remain...

i heard that a faraday cage is often used in shielding e.g. sensitive electrical equipment. I was just wondering, because, in http://socrates.berkeley.edu/~fajans/Teaching/cartoons/Shielding/TestChargeShielding_files/frame.htm it seems that the electric field is not zero at ALL times. i.e...

If Earth could be considered the only body acting gravitationally on a length of rope, if the rope say a 1 mile length, is aligned in a straight line with the center of the Earth in some orbit, when the rope is free, will it tend to curve to the shape of the orbit, or will it fall in on itself...

Quick question (...and I hope I have this in the right forum) Does anybody know anything about the effects of inhaling dust particles of anodized aluminium? I am especially interested about finding information on any possible negative effects on the respratory and cardiovascular systems...

I have heard that while pi is known to many millions, even billions of decimal places, gravity makes it both fundamentally and practically impossible to measure pi to more than 10 significant figures. I find this to be a very strage theory, and have never heard of it before. I am also finding...

As the temperature of a body is increased, how does the frequency of peak intensity change? How does the total amount of radiated energy change? When the dimmer control is used to increase the voltage to the bulb, the temperature of the glowing filament increases. As a result, the color...

An increase in the OH- in a solution would result in an increase in alkalinity (baseness). an increase in acidity. a pH of 7. a decrease in pH. i think it would be - an increase in alkalinity, but I am not sure help!

Hi, when two cylinders in contact, but not parallet to each other (skewed), are rotating, there is a development of forces between them which tends to push one cylinder along its rotation axis and the another one to the opposite side. In other words, there will be translation movement between...

Can some one spread more light on coanda profile its effects ,calculations etc

I was just reading "A Briefer History of Time". Stephen Hawking describes how your body would be torn to shreds by the increasing forces from gravity as you approach a black hole. I've read this from other sources as well. However, from what I understand about general relativity, gravity...

If I remember right this is the active ingrediant in motion sickness pills - if high doses of dramamine (for example) are taken you are able to hallucinate. This is considered a deliriant? How would you rate the power of this drug compared to any other substance or device that creates...

I am interested in measuring the effects of a magnetic field on an electron in a tunneling state. I know very little about solid state and I have very little experimental experience. In order to learn what is required to perform such an experiment, I thought I would pose my question here...

I am obtaining data with a sample rate of 6250 samples/second on a digital oscilloscope. Ideally, I am obtaining a sinusoid output through a system from a sinusoid input. My expected results through the system are lower in amplitude than I am actually recording. I have some reasons for why...

What happens with causality at the Planck scale? Can effects "precede" causes? I would like to know what happens with causality at the Planck scale, explained in "educated layman" terms, if that's possible... :) Might effects "precede" causes in time? Do we have to redefine causality at the...

Homework Statement This is starting to get a bit trick because of mixed information. Anyways, does anyone know the effects of osteoporosis in terms of short term versus long term? Homework Equations N/A The Attempt at a Solution Spine fractures caused by osteoporosis are likely...

Hi.. Im trying to figure out what the affect of HCl on a magnesium strip at different concentration levels has? I can't figure out a 'scientific' response and therefore can't formulate a hypothesis :/ Any help will be appreciated.

This may be a simple question for some of you but it has baffled me for a long time. When we say that spacetime is curved, do we mean that from a flat space of a higher dimension, our spacetime would appear curved, in the same way that the surface of a sphere looks curved when viewed from...

Please clarify the following view: An EPR-Bell experiment - when one particle in a Bell correlation is measured, this instantaneously affects the properties of the second particle. To me this seems as if information concerning the measured particle has "arrived without travelling" to the second...

I was curious as to how planetary type spherical bodies form. Specifically, I was curious as to how the gravity affects the nebulous particles moving within themselves just prior to a solid planetary body forming. Is it not true that gravity is essentially zero in the center of a planetary...

When a pendulum is moving will the length of the string that the bob is attached to appear to be contracted?I have this doubt as the string is sometimes in direction of motion and at one point absolutely not in the direction of motion

If the star ionizing an HII region suddenly doubled the radiation emitted, would that increase or decrease the temperature? I feel like the expansion of the region would cancel out the increased energy, but I don't know.

Homework Statement n a Rutherford scattering experiment a target nucleus has a diameter of 3.5 10-14 m. The incoming has a mass of 6.64 10-27 kg. What is the kinetic energy of an particle that has a de Broglie wavelength equal to the diameter of the target nucleus? Ignore relativistic...

Wasn't sure if this is exactly the right place for this, but it seemed the most relevant. Homework Statement Ok, I've recently started some research for my A-Level project, and I decided to look into the polarising effects of plastics. When two polarising filters are positioned one after the...

Why is it that in a formula: f(x)=2x^4...), why is it that the exponent actually BENDS the line that the fomula makes when it is graphed? I know about the high and low point in algebra two (that's what I'm taking), but i just want to know WHY does an exponent BEND the line? CD

Andre, this is mainly concerning your work, especially with your claim that CO2 is not a gas that causes global warming. From what I have gathered (and I hope I don't make a fool of myself by saying this) but you have argued that CO2 levels have risen over periods of cooling in the past...

In the 1999 paper published in Nature by Markus Arndt et al entitled "Wave-particle duality of C60 molecules" he states: The fullerenes are of course in this funny state of superposition as they are 'falling'. Couple questions: 1. Is this drop of 0.7 mm identical to what any object...

I am having trouble understanding the concept of the effects on an orbit. The question asks if we replaced the sun with a rock of the same mass, would Earth's orbit change? I think it doesn't because orbits don't change because of its orbital energy. but I'm not sure because i wonder if the...

Hi! My Physics introductory book states the following: "A dew point is a state defined by the temperature to which the air has to be cooled isobarically (with constant absolute humidity) for the vapour to become saturated." Humidity is defined as m/V, where m is weight of the vapour, V is...

Is it possible to remove a proton from an atom and then as a result will the element of the atom will change? Would anything else need to be remove to keep an equal balance in an atom, ex. neutron or electrons? How much radiation would be created by removing a proton.Is more rediation...
