Why do some batteries don't recharge?
I would first have the alternater tested to be sure that it's good. If it is then make sure you're getting voltage to it when you hook it up on your car. If you take jumper cables off and it dies you're not getting voltage to the alternator. You could have a bad battery and if you're alternator is working right the car would still stay running even if you take jumper cables off. Check all wiring going to alternator thats more than likely your problem also check your grounds and ground wire to the alternator.
I had the same type of problem. It was a bad fusible link. I just ran a wire to the 10 mm bolt on the back of the alt. to the battery. This wire has to be thick though. And I would definelty put a battery charger on the battery. Also check all grounds to the motor.
How much does a machinist make in a year?
in Washington state the journeyman union rate for an ironworker is $33 per hour as of 2007, probally higher now.
What was technology like in the 1960s?
Aside from computers (which were mostly used by businesses and the military), technology was all analog. Long-distance communications relied heavily on terrestrial microwave relay networks and undersea cables. The first transatlantic communications satellite was launched in 1965. Real-time control of dynamic systems, including missile guidance, was done with analog computers, as digital computers were not fast enough. Huge advancements were made in chemistry, leading to the development of many new synthetic materials. Integrated circuits typically contained fewer than 100 transistors and were still too expensive for consumer applications; consumer electronic products used discrete transistors, billions of which were produced.
They didn't have as much electricity so people had many non electrical appliances. Homes in the 1960s had basically the same electrical appliances that they do today. However, fewer homes had air conditioning, particularly in northern climates, and fewer homes had dishwashers.
They lived on a smaller income and therefore couldn't use as much electricity.
Electricity was much less expensive than it is today, so people didn't need to conserve as much. Homes were not as well insulated as they are today; those with electric heat probably used a lot more electricity than anyone could afford today.
Things like fridges were around and lawenmowers that didn't use petrol but these were much heavier than current mowers.
Actually, push mowers are much lighter than current lawnmowers, because they don't have a fifty-pound engine. For some types of grass, reel-type push mowers still do a much better job. The first practical barcode scanner was made in 1966.
The original Apollo 11 astronauts were burnt alive inside Apollo 11 during takeoff because they couldn't get the hatch open when the cock pit caught fire. thAt was 1969
Apollo 1 (not Apollo 11) astronauts died in a cockpit fire during a test rehearsal, about a month before their scheduled launch date. That was January of 1967 (not 1969). The next manned Apollo mission was Apollo 7, which orbited the earth for 11 days, followed by Apollo 8, 9 and 10, each of which orbited the moon. The Apollo 11 mission, in which Armstrong and Aldrin walked on the surface of the moon, was in July, 1969.
Technology was bad back than cause electricity was no good back in the 60s they used some stuff that we have now but their was'NT as good as our tech now. Stuff like computers,phone,and Printers.
It can transfer information wirelessly form one enabled device to another. It can transfer information heedless of blockages or obstructions that may be in the way in form of walls, people, cars, etc. It is relatively safer than infra-red enabled devices although it can only function within 30 feet or 100 feet in the case of a very powerful device.
JFET = junction field-effect transistor. The transistor design is to restrict/control the current in the channel by expanding or contracting the depletion region, hence the channel cross-section, with a gate signal. The gate is the junction in JFET, compared with using oxide in an MOSFET.
Upon research that I did on the Insignia TV that I bought I was able to determine that, as Best Buy's in-house brand name for electronics, the contracts for production are put out for bid and won and produced by various Chinese, Taiwanese and other third-world country manufaturing companies. No single company is the source company for Best Buy's Insignia products, it just depends upon the specific electronic item, its model or features, and the time at which the contract was awarded.
When was the cassette player invented?
1973! That the cassette by itself but the cassette player came out in 1980
Nope. This cannot be correct, because I owned a cassette player and plenty of cassettes for it too, at least 3 years before that (when I was in Vietnam). And they were not a new technology when I bought mine. I also owned an 8-track tape player with tapes. I always wanted a reel-to-rell because they were supposed t be the best of all. But I never got around to getting one.
Identify the different types of electric circuit?
Branch circuits serving more than one outlet or load are limited by the National Electrical Code to three types:
Circuits of 15 or 20 A may serve lights and appliances; the rating of one portable appliancemaynot exceed 80% of the circuit capacity; the total rating of fixed appliances may not exceed 50% of circuit capacity if lights or portable appliances are also supplied.
Circuits of 30 A may serve fixed lighting units with heavy-duty lampholders in other than dwellings or appliances in any occupancy.
Circuits of 40 or 50 A may serve fixed lighting with heavy-duty lampholders in other than dwellings, fixed cooking appliances, or infrared heating units.
How do you get luigi in Super Mario 63?
Mario is one of the starter characters in Pokemon: Paper Mario. It is a hack of Fire Red, by a team led by RedYoshi. It is not finished, but you can download up to Bowser's Takeover with the Alpha release, available here. http://www.pokecommunity.com/showthread.php?t=171268
Benjamin Franklin discovered electricity. Afterwords, Thomas Edison invented the light bulb. Fun fact- "I have not failed 1,000 times. I have
successfully discovered 1,000 ways to NOT make a light bulb."
How much outlet to 20 amp breaker?
No. Receptacle is rated at 15 amps and the wire that feeds it will also rated at 15 amps. Since it will take 20 amps to trip the breaker the wire will be become overloaded.
The above is true only if it is a single dedicated outlet. You can use 15A duplex outlets
on a 20A circuit, ie: kitchen and dining room outlets per the National Electrical Code.
Is a computer small enough to fit in one hand?
Mostly any handheld device is a computer. Your iPhone, calculator, etc. It depends on what you what the computer to do. A calculator will obviously calculate numbers and equations for you (perhaps in graph them).
An Iphone (or any other internet abled phone) while allow you to search the web and look up maps, etc.
GPS is a computer as well. (Global Positioning System) GPS uses satillite to position where you are at.
There are many computers that do certain things that help us move along through life more easily.
How do you calculate inventory turnover?
This is a very simple calculation. Days to Sell Inventory(or Days in Inventory) = Average Inventory / Annual Cost of Goods Sold /365 Average Inventory = (Beginning Inventory + Ending Inventory) / 2 To calculate this ratio for a quarter instead of a year use the following variation: Days to Sell Inventory (or Days in Inventory) = Average Inventory / "Quarterly" Cost of Goods Sold /"90" Average Inventory = (Beginning Inventory + Ending Inventory) / 2
What is the best age for a kid to get a cell phone?
You should get a cellphone when you think your child is mature enough and responsible enough for one. If you give your child a cellphone when their not ready they might do things with it like show it off at school or they might drop it multiple times and it will most likely be an accident when they drop it. That will show you how responsible they are. You should also get it if they are going to be going out alot(like school) but it depends if their responsible, give it to them. If they are not responsible and they go out alot well don't give it to them.
Lit up 30 years ago the laser diode is the basis of all of the world's cheap lasers.
A ruby laser (depicted earlier) is a solid-state laser and emits at a wavelength of 694 nm. Other lasing mediums can be selected based on the desired emission wavelength (see table below), power needed, and pulse duration. Some lasers are very powerful, such as the CO2 laser, which can cut through steel. The reason that the CO2 laser is so dangerous is because it emits laser light in the infrared and microwave region of the spectrum. Infrared radiation is heat, and this laser basically melts through whatever it is focused upon. Other lasers, such as diode lasers, are very weak and are used in today's pocket laser pointers. These lasers typically emit a red beam of light that has a wavelength between 630 nm and 680 nm. Lasers are utilized in industry and research to do many things, including using intense laser light to excite other molecules to observe what happens to them.
Why are the notebooks usually more expensive than PCs with comparable power and features?
Because the engineering and design is more critical due to using much smaller parts. Miniaturization of the hard drives is more expensive and the heat sinking of heat producing items on the motherboard is more critical. There are a number of reason, but those are some of the most important ones.
How do you fix a wet electronic device?
There are several ways to try and dry a wet device, like an iPod or cellphone. They work to differing degrees in different times, and can be used together or alone.
- Place it in a warm, dry room for a few days, testing daily to see whether it has dried yet.
- Turn a hair dryer to low and wave it over the device from about a foot away for 20 to 30 minutes. Test it, and continue drying for another 20 to 30 minutes if necessary.
- Place it in a cup of rice (rice absorbs water, but won't clog up the device).
Using a hair dryer is a very bad idea: all it does is push the water further into the cracks and crevices of the device, making the problem worse. Rice also does not work, as it does not absorb moisture from the air, and it only absorbs a significant amount of water if the water is boiling. The only reason people say it works is that sometimes, if the device wasn't too wet to begin with, it just dries out by itself. It would have dried out without the bag of rice, but since it was in the bag of rice, people think it was the rice that dried it. Not so. The device just dried by itself.
By far the best way to dry out wet electronic devices is with silica packets. You know those little packets you find inside your new shoes, or in your medication bottle? They usually say "Silica - Do Not Eat?" These packets draw in and absorb moisture. They are put in shoes and medication bottles to keep humidity and moisture from ruining the product. Sometimes in medication bottles they come not in packets, but in little white plastic cylinders.
Every time you find a silica packet or plastic cylinder, save it. Put all of them in a sealed plastic bag, so they stay fresh and do not absorb moisture from the air. Next time one of your electronic devices gets wet, wrap it in a paper towel and seal it up in the bag with the silica packets. Wait 3 to 5 days. Your device should be good as new.
Several months ago I dropped my TV remote into a bucket of water. I didn't even notice at first, so the remote stayed submerged for nearly 10 minutes. After shaking the excess water out of it, I wrapped it in a paper towel and put it into a Ziploc bag full of silica packets and cylinders I had saved. Five days later I took it out, and it was good as new. It's still working perfectly, some 8 months later.
How many cells are in a battery?
According to WikiPedia (http:/en.wikipedia.org/wiki/Rechargeable_battery), the nominal cell voltage of a Lead Acid wet-cell battery is 2.1 volts, this implies there are 6 cells in a 12 volt Lead Acid wet-cell battery.
What was Benjamin Franklin's most famous experiment?
Benjamin Franklin Rocks Benjamin Franklin (January 17 [O.S. January 6] 1706 - April 17, 1790) was one of the most important and influental Founding Fathers of the United States. A noted polymath, Franklin was a leading author and printer, satirist, political theorist, politician, scientist, inventor, civic activist, statesman and diplomat. As a scientist he was a major figure in the history of physics for his discoveries and theories regarding electricity. He invented the lightning rod, bifocals, the Franklin stove, a carriage odometer, and a musical instrument. He formed both the first public lending library and fire department in America. He was an early proponent of colonial unity and as a political writer and activist he, more than anyone, invented the idea of an American nation[1] and as a diplomat during the American Revolution, he secured the French alliance that helped to make independence possible. Born in Boston, Massachusetts, Franklin learned printing from his older brother and became a newspaper editor, printer, and merchant in Philadelphia, becoming very wealthy, writing and publishing Poor Richard's Almanackand the Pennsylvania Gazette. Franklin was interested in science and technology, and gained international renown for his famous experiments. He played a major role in establishing the University of Pennsylvania and Franklin & Marshall College and was elected the first president of the American Philosophical Society. Franklin became a national hero in America when he spearheaded the effort to have Parliament repeal the unpopular Stamp Act. An accomplished diplomat, he was widely admired among the French as American minister to Paris and was a major figure in the development of positive Franco-American relations. From 1775 to 1776, Franklin was Postmaster General under the Continental Congress and from 1785 to 1788 was President of the Supreme Executive Council of Pennsylvania. Toward the end of his life, he became one of the most prominent abolitionists. Franklin's colorful life and legacy of scientific and political achievement, and status as one of America's most influential Founding Fathers, has seen Franklin honored on coinage and money; warships; the names of many towns, counties, educational institutions, namesakes, and companies; and more than two centuries after his death, countless cultural references.
Can you put plate in microwave oven?
It all depends on the construction.
Most plates made of pottery are OK as long as they do not have design containing metal. Some decorated plates have a gold stripe around the edge or in the design, avoid these. It is best to use cheap, white or plain plates.
Plastic plates are OK.
Why should there be violent video games?
Absolutely not. Humans are violent in nature at times, and movies are a form of self expression. It is much more safe to have violence expressed and enjoyed through movies than to have it actually acted out in real life.
Which big screen TVs are better lcd or dlp?
Hi,
They're both good and at the same time, they both have their specific problems, depending on the manufacturer, size of screen and intended uses.
The LCD sets are becoming higher in resolution and are now comparable to the dlp sets. What I would suggest though, it that you decide which one you like looking at best and then at least decide on what type, LCD or DLP you'd rather have.
Keep in mind that the big box stores spend a lot of money on making sure the TV's displayed in the showroom display the highest quality picture. That's usually a high definition DVD or at the least, a HD satellite feed. Chances are that when you get it home, and unless you have all HD equipment, you'll not see the same picture quality you saw in the showroom.
With all that being said, this is where you have to do some homework. Check Consumer Reports, keeping in mind that they usually rate the new models and product's service history hasn't been established since the TV's are so new. Also check 'blogs and answer boards on the internet. Usually there, you'll hear about TV's that are a year old or older. Why do that? Because the manufacturer's past product lines and complaints could be a good guideline on what to expect.
Once you've gathered all your information and have made your decision, do one last thing: BUY THE EXTENDED SERVICE CONTRACT! The costs to have service come out and the costs of the parts could prevent you from being able to repair your set once the factory warranty runs out. The parts for today's TV's are very expensive and sometimes as much as the original cost of the TV.
Hope this helps,

He did not invent the iPad.
And if you mean him being the first, he wasn't either.
The iPad was created to show the people of Microsoft what a real tablet can do. In response to when the tablet was introduced by Microsoft in 2002.
