Dual Definition and 373 Threads

I have an acer aspire30002 and i connected a dell flat panel monitor to it. The thing is I can never get them to display separate screens. I got them to display the same thing earlier but now only one at a time. Does this mean that the video card does not support dual monitors?

While I've worked with an awful lot of motors, including making simple ones and repairing several others, I don't know the technical aspect of what governs the no-load speed of a DC unit. Specifically, I have 3 really nice 12VDC 1/2hp wheelchair drive motors with gear trains. They're extremely...

Ok, so we learned about rail guns today (they are so freakin' cool), and I understand how it moves one rod down the rails... however, what happens if there are two? Won't both move down the rails (away from battery) since the current is flowing clockwise, or will they repel each other?

I want to get into the R&D team at one of the big 3. I am currently a dual major in electrical engineering and mechanical engineering, which is a 167 credit hour program. I am currently a second semester junior in EE and a second semester sophomore in ME. I am going the EE/ME dual major route...

In my lecture note about tensor it states: As element of integration over the hypersurface it is more convenient to use the 4-vector dS^i , dual to the tensor dS^ikl: dS^i = -1/6 e^iklmdS_klm ,dS_klm = e_iklmdS^i What is the meaning of dual? How the -1/6 comes from? yukyuk

I am reading ahead for my Group Theory introduction to QFT and I have a question about the dual representation. If the dual representation is the same as the ordinary representation, that is to say the ordinary representation is "real", how do we represent anti-particles in this case? This...

Does anyone know if anything in your average room (besides a kitchen) emits enough heat to decently warm up a piece of food? I had a feeling a CRT monitor would do but i only have an LCD now and i want to heat up this cherry turnover! Oh, and I only use CF bulbs in my room...

If you have a five gallon jug of water with a 1/2 inch spout, and it is laid on its side, because there is no other opening in the jug it empties as air spills into the spout and replaces the water, but if the jug would have another 1/2 inch spout on it, now on top of the laid down jug, Would...

I've worked it out and due to offering limitations it will take me 3 more years to do the former, and 2 more years to do the latter. I've already been in university for 2 years. The courses I'd need in order to accomplish both are listed below: For the dual major in physics/math with...

dual major in chemistry and physics or physics and math oops, I meant dual major in chem and physics OR physics and math. So what do you think is better for someone who wants to go into theoretical physics? Should I go for a dual major in chem and physics and a minor in math, or a dual...

Hi, could someone show me how to express \frac{\partial G^{\mu\nu}}{\partial x^\nu} = 0 which are Maxwell's equations, G is the dual tensor, in terms of the field tensor F: \frac{\partial F_{\mu\nu}}{\partial x^\lambda} + \frac{\partial F_{\nu\lambda}}{\partial x^\mu} + \frac{\partial...

Hi, I have a question about calculating the error of the transducer. A pressure transducer exhibits a temperature sensitivity of 0.05 units per degree Celsius and a pressure sensitivity of 5 units per MPa. If the temperature changes 30 degrees celsius during a measurement of a pressure of...

Fisrst excuse me if the topic has already been addressed. I have made a quick research and i didn´t fint it. I talk about these: http://news.bbc.co.uk/1/hi/sci/tech/4357613.stm A preliminar interpretation of it was as a black hole. Someone suggested me to do a researtcho for...

I realized some time ago, that there was no singular term that refers to both genders! This is really quite annoying, since I've been using "him/her" quite a bit, and it gets tedious. Am I mistaken, and there actually is one, or can we all just agree on one? :D:D:D:D:D I propose "xem"...

Here's one from my HW: Two blocks are connected by a massless string on a triangle with a pulley at the top corner. The angle of the left corner is 35 degrees. the angle on the right is 60 degrees. the left block equals 7kg and the right is 9 kg. mu k = 0.25 Determine acceleration of...

How much can it boost PC performance? Worth it or not?

My friend has a problem. He has a computer that has one working internet and his other computer's internet is down. They are in separate rooms but are connected by an extension cord. They are both connected to the same modem, any ideas why one is working and the other isnt? (They share the same...

I don't know why Britain wants democracy everywhere especially in commonwealth countries, since they have got a queen of their own. Is that democracy? The invaded Iraq to free it from a dictator who had his own parliment. The queen has got a parliment shouldn't she be thrown off. It says in a...

What do they mean w.r.t Cell Phones ?

Would it be possible for binary planets, or even a planet and it's moon, to simultaneously sustain life? I know the odds of a planet having life on it is very low, but for a planet that does (earth) would it's sister planet or moon be able to sustain life as well? Maybe if the bodies are the...

Hi everyone... I've been struggling with a physics problem for 2 days now... I'm really not sure what to do. Problem - A pair of 10.0 kg masses are suspended from (massless) strings wrapped around a dual pulley. The radius of the smaller shaft on the pulley is half the radius of the...

Can someone give me the formulas for single a two slit defraction of light. And please explain what te variables mean. Are these right? Wave length = xd/L Wave length = yw/L If these are right can someone please explain what the variable stand for because...
