How do i know if my car is being tracked by someone?

It all depends on what type of information the device is intended for, for the most parts it's somewhere near the front end of the vehicle, but because of the every changing size and uses of GPS devices it can be anywhere.

How did electricity change the world?

Electricity has had an enormous impact on society, considering how much we have come to depend on it. Nearly everything Americans hold dear is made possible by electricity-to think of life without it is mind-boggling. While I think we have developed a kind of over-dependency, there is no getting around the fact that it has molded the course of human civilization-both for the good and for the better.

Why has the toilet started making a noise when flushed?

A toilet may be making noise if parts are wearing out or a problem exists in the plumbing. It may be a good idea to contact a plumber to see if there is a bigger problem.

How do you measure polarity?

In a DC circuit, just connect your meter across the source or electrical bus. The meter, because it is one of the newer digital ones, will work regardless of which way the leads are connected. If the leads are plugged into the meter correctly, the investigator need only look at the sign associated with the reading on the meter and the position of the leads. If the reading on the meter is "13.6 V" on a DC setting, then the red lead is connected to the positive side or negative rail, and the black to the negative side or negative rail. Conversely, if the reading is "-13.6 V" on a DC setting, the red lead is on the negative side or negative rail, and the black lead is on the positive side or positive rail. The DMM is a wonderful innovation and will allow someone making measurements to not have to worry about which way to connect the leads - as long as that someone pays attention to the sign displayed with the voltage reading.

What is called to connect the one CPU to many monitors?

http://support.microsoft.com/default.aspx?scid=kb;en-us;307873 This article indicates that WinXP supports up to 10 monitors. Many video cards will support 2 monitors. If you install two such cards, then you may connect 4 monitors. Add video cards as long as you have empty PCI slots in the PC.

Why has an led light got a flat side?

The flat side marks the cathode, or negative wire coming out of the LED. Make sure that the wire on the flat side is connected to ground.

Why can't you put metal in the microwave?

The best answer (with just a bit of technical stuff).

Ask around to find out if using metal in a microwave is okay, and the answer is often a no. A no is a safe answer, and that's for sure. There are instances where metal is absolutely to be avoided. Metal utensils are a no-no, and the use of plates with metal designs should be avoided. That said, there are times when a bit of foil greatly helps with things and can be used safely. But the situations will vary. With that in mind, let's look at, "Is it save to put metal in a microwave oven?"

It may be yes, or it may be no. Here's a suggestion. Let the manufacturer make the call on this one. Generally speaking, the magnetron (the component in the microwave that generates the microwave energy) won't be harmed by metal in the cavity (the cooking area). But any metal within the cavity might act like a microwave antenna, and this may create arcs, and even start a fire within the cooking area. This will melt and burn things within the cavity, and almost certainly damage the door, which will make the oven unsafe to use (if it doesn't actually disable the oven). But setting aside those issues, let's look more closely at the microwave and how it should be used.

No one on this board can tell for sure without the owners manual or the model number of the machine in question (so one could look at the owner's manual) whether metal can or cannot be used in a given machine. "No" is a safe answer, but it may not be correct. A microwave has some cooking capabilities that may not be obvious, and anyone who owns or uses one of these puppies should know whether or not something like foil can be used inside it. There are even some microwaveable "fast foods" that have a bit of foil in the microwaveable package. Additionally, some microwave ovens allow a bit of foil over a portion of a food item being cooked, like the ends of the drumsticks on a bird. If the manufacturer's manual is not handy, it may be possible to go to the manufacturer's web site and actually view it online. Certainly the pamphlet can be had by ordering it. Get the manual. Read it. There might be several things in there that weren't obvious. Like whether or not foil can be used in the oven. That's why the correct answer may be either yes, or no.

If you have any doubts or issues, or you are not familiar with the manufacturer's instructions for a given unit, the "no" is a safe default answer and should be applied. But further investigation and thinking is in order if a microwave user wants to get the maximum out of a unit and really develop insight into the truth in the answer.

Surf on over to the USDA page with microwave use and safety suggestions. Scroll down to the section on the use of foil and see what they have to say. That's a good place to start, and you're just a few keystrokes and mouse clicks away right now.

How did the phonograph change the world?

Jazz as a musical movement came about in the early 20th Century, first originating as "The Blues", which took influences from African American work songs, field hollers, spirituals, gospels, and African oral musical tradition, forming them into a new, call-and-response style of music that became one of the very foundations of popular music today. From the early blues roots, Jazz evolved into a myriad of other styles, such as Big Bang Swing, Bebop, Modal, Latin, Free Jazz, and Fusion. Not only did Jazz create and influence so many different types of music, but it also opened the doors for musicians who were not classically trained to show their stuff and be heard. The rich freedom provided by solo improvisation is a feeling unlike most, especially when you're surrounded by great musicians. As perfectly said in the comedy series The Spoils Before Dying: "Ah, the sanctuary of Jazz. The safety in no safety. The music lived in life while life is happening. Jazz is life's adventure set to rhythm."

How does a flashlight work?

A flashlight has a power source (usually ordinary batteries), a light source of some sort (a light bulb or LED, for example), and some electrical wiring to connect them, with a switch to turn it on and off. The power source makes the light source give off light.

What are ESD precautions?

ESD stands for Electrostatic Discharge. You should avoid the possibility of static building up when working with PC components by ensuring that you are grounded at all times. You can do this by using a special anti-static wristband, which is available very cheaply. Alternatively, touch the chassis of your PC case often, or hold the chassis with one hand while touching any sensitive components.

Can speakers connect to a VGA port?

No. VGA is for the monitor. Speakers connect to the audio output using a mini-phone plug. On most machines, both the plug and the jack into which it goes are colored light green.

Does the glow of bulb depend on current or voltage?

Since the bulb has a constant resistance, increasing the voltage will increase the current which will increase the brightness until the bulb blows in a flash of light.

Ohm's Law governs this process where Volts = Current x Resistance.

Another Answer Incandescent lamps do not have a constant resistance, as their resistance increases significantly with temperature. In fact, the 'hot resistance' of a lamp filament is around 10-18 times higher than its 'cold resistance'. The temperature increase, of course, is due to the current passing through the filament. This means incandescent lamps do notobey Ohm's Law and are, thus described as being 'non-ohmic' or 'non-linear'. However, to answer your question directly, the rated power of a lamp only occurs at the lamp's ratedvoltage. Even a small reduction in voltage will result in a significant loss of power and, thus, brightness. So, in this sense, a lamp's brightness is determined by the voltage applied across its filament.

How do You discard an old computer?

Well many have been there and the answer is responsibly. Your first option is to throw it away in the plain garbage, but it is irresposible and hurts the environment, and it may be illeagel in your state so that's out. The next way is recycling but you may have to pay a fee. You could trade it in to a store like Computer Renaissance and they will pull the good stuff like the RAM out and recycle the rest for free, if it is new enough you may get credit towards the purchase of othe computer equipment. My advice is is if it has Windows 98 SE or better take it to a private school and donate it since they are not federally funded and so they can only afford Windows 95 computers.

Why is apple a success?

Key Success Factors

Core Strengths

Apple has numerous internal strengths that make it a successful and

competitive company. For one, Apple has a powerful footing in the personal

computer market by being "different" with its innovative style and ease of use.

Its operating system is developed in house, leaving it free from the tangles of

the dominant Microsoft operating systems. This gives apple a very large degree

of control over its product in the physical appearance, specifications, and overall

usability. Apple does all this while keeping its Macintosh computers compatible

with existing PC computers. Additionally, Apple fosters a research intensive

office environment and is constantly releasing products with the current trends

and styles as seen through its latest iPod and Mac mini. This makes Apple one

of the biggest innovators in the computer and portable music industries, being

first to bring new and creative ideas to the market.

Core Weaknesses

Due to their research intensive nature, Apple has high R&D costs, which

means that Apple is far less cost effective in a very saturated market. While they

currently hold 90% of the portable music market, Apple is constantly relying on

innovation to keep it ahead, putting the company in a risky position if its R&D

does not come through.

Moreover, Apple has a hard time selling the Mac

computer to many customers do to the perception that the Macintosh is

incompatible with other PCs and software. In other words, customers get scared

of an operating system that looks different then windows and assume it doesn't

work the same. While this is not true, it hinders the ability of Apple to steal

away existing PC users to grow its market share.

Finally, Apple has problems

with some customers due to the high prices of many of their products. While

this has not hindered their sales in the portable music market yet, it can be

traced to problems within their computer market sales.

Market Opportunities

Within the industries that Apple competes there are numerous

opportunities for increased market share and growth. Since Apple is already

recognized as one of the main leaders in the portable music market they have

the ability to further increase their company image and quality

image reputation. This will allow Apple to maintain their already

well established clientele as well as attract new customers. Within

the personal computer market Apple is expected to sustain

substantial market share gains in 2005 because customers are

awaiting the launch of Windows Longhorn for Microsoft.

On the portable music side of things, it is speculated that if Apple were to

release a flash-memory based mp3 player that its music business

would be worth close to 5 billion by 2006.

As a final point, many speculate that Apple's entire line of Macintosh computers will gain market share due to the halo effect of the iPod.

Market Threats

There are many potential threats that Apple faces everyday. The primary threat that they face is the rapid advancement in technology. Since most people judge the computer on the speed (GHz) of its CPU, Apple has had a hard time with customers considering the Macintosh inferior in

speed to the PC. Although, recently the new Macintosh

computers have begun using 64bit technology as opposed to the PC which is still primarily using 32bit technology.

This has given Apple a slight edge to their

speed problem. Therefore, Apple must make sure that

they stay up-to-date and on the cutting edge of

advancements and innovations. One slip in their R&D

department and Apple could lose an enormous amount of their market share.

One final note is the threat of Napster, Apple's primary competitor to its iTunes

music service. Napster has begun aggressively marketing its new service which

allows unlimited music downloads which are "rented" to the mp3 unit while the

subscription is active. This service, costing only $14.95 a month, is the first

serious challenge to iTunes 99 cent per song download business strategy.

Whether or not Napster will effectively unseat Apple is yet to be seen, but shows

the vulnerability of Apple's portable music market share.

Competitive Strategy Analysis

In such a highly competitive industry where superior quality and brand

image are key success factors for a computer company, it is necessary for

computer companies to become cost leaders or differentiate themselves by

offering a unique product. Apple has become known as a computer company

that has innovative and stylish computers and music playe

What are opinions on whether or not mature video games should be banned?

I think they shouldn't be banned because they have 18 year olds playing them. In my opinion, a complete ban would be very out of order and is very unlikely to happen. As mentioned above, they are designed for people of a certain age-group and should not be sold to people younger than the age-group they are designed for. If a child buys a rating 18 game somehow, it is up to the parents of the child to remove it from their child's possession and to contact the police for a violation of the law. A total ban would ruin it for those over the legal age to play the game...

Should kids get cell phones?

There is a talk about mobiles are not safe. People say that if the child is under 16 and has a mobile they might get brain cancer. If your child is begging for a phone wait till there in secondary school. Apparently everyone at high school has one and you don't want them to feel left out. In till they are 16 say that he/she can only use it for short calls and texting. That's what i recommend.

Juliet Schor, a professor of sociology at Boston College in the US and a leading researcher on children and consumerism, claims that children's 'involvement in consumer culture causes dysfunction in the forms of depression, anxiety, low self-esteem, and psychosomatic complaints'.
