How does a synchronous motor operate?
It works on the principle of "MAGNETIC LOCKING". When two unlike poles are brought near each other, there exists a tremendous force of attraction between those two poles.
What is the best setting for an amp?
I'd think that first off, a comfortable listening level might be your best choice and where to adjust that depends on your speakers and how much power your amplifier has. Definitely not full volume as it can be rough on the amp and the speakers. Set the bass to what's pleasing to your ear, as well as the treble, etc. If you use a graphic equalizer, all the better for more accurate and `pleasurable' adjustments. If it sounds distorted, it's not good and very fatiguing to listen to because you're either over driving the amp or exceeding the capability of your speakers, or both. Its' the same way with it being too loud too, as this will cause listener fatigue just as quickly as distorted sound. And if blood starts dripping from your ears, shut it off and get to the nearest hospital!
What are the different uses of electricity?
Using electricity is a tough thing to conceptualize-we draw it from our sockets to power computers, stereos, and appliances, and it indiscriminately runs our refrigerators, microwaves, and air conditioners. We're even sucking down electricity when our appliances are off, thanks to phantom power. It all amounts to the sapping of resources-whether your electricity comes from coal burning plants or nuclear power-and we could all stand to cut down.
Yet it remains a relatively abstract concept, that is, we're never really sure exactly how much electricity we're using-unless we have an ever-useful electrical use calculator on hand (or more accurately, online).
Take a look at the calculator on Michael Bluejay's electricity website to find out exactly how much wattage you're using-and how much money it's costing you.
Once you've broken down your electrical usage, it makes it much easier to isolate problem areas and cut back. Leave some of your lights on all day or all night? Each one could be costing you around 30 dollars a year.
And even though turning off a few lights or unplugging your computer may not seem like momentous acts, if everyone were to do the same, we could relieve some serious strain on natural resources that have already been stretched thin.

Where did the word electricity come from?
It came from William Gilbert. As he was the first to discover anything about it. When I can't tell you but someone else will know.

Is there any technology to control the brain waves?
There is a technology called brainwave entrainment that uses audio to alter or influence brainwave activity. Basically, you listen to a special audio CD with a pair of stereo headphones. In one channel a particular frequency is introduced, and in the other a slightly different frequency is played. The difference between the two signals is called a beat frequency. The developers say that the brain interprets this beat frequency, and causes brainwave synchronization at the beat frequency between the two hemispheres of the brain. There are a number of commercial producers of these disks. Hemi-Sync, HoloSync and Dr. Jeffrey Thompson are some of the more well known producers. I've tried them and found them to be very relaxing. Whether this is due to a measurable effect on my brainwaves I don't know but there is something happening when I listen. I prefer the Jeffrey Thompson CDs because they are more musical. Visit their websites for more info. There are also software packages that allow you to create you own brainwave entrainment audio. Yes. It's called the electric chair, and it makes the brain waves stop very quickly. I loved the last answer best but yes there is. It's called an alphawave inducer. Basically, a set of flashing lights that fill your entire field of view (that parts important) and that blink between 3 and 7hz. The blinking lights cause the brainwaves to sync with them. I've built one once using plans from an electronics mag and bought one that I use now for about $50. There are also high end devices (called NovaPro or something like it) that do the same thing for hundreds of bucks. And yes they really do work. Great for relieving stress or getting rid of a tension headache. The first one I built was a set of swim googles with leds in the center of them and a rubber coating poured over them. The electronics was a quick 555 timer circuit run off a 9 volt battery. Nothing complicated.

There are two main definitions for resolution:
1- a decision to do a certain thing is a resolution; "I made a new years resolution to be a better person"
2- the amount of graphic material/detail that can be shown on a computer screen; "My computer monitor has a resolution of 1280 x 960"
What is the difference between adapter and charger?
An Adapter usually convert AC current into DC current with low output voltage for a device like camera, speaker, tape etc which uses to operate 3, 6, 9, 12 volts or whatever.
but a Charger is used to charging batteries (any type) like laptop, mobile, camcorder batteries etc. It also convert AC current into DC current with low voltage but with high charging power.
