Does the trunk light bulb in a 1999 Toyota Avalon look like a fuse?
I have a 1998 Avalon and my trunk light looks like a fuse. I took it to a couple of auto stores and they didn't sell it but I've looked it up on Amazon and it's actually called a fuse lamp.
You just need to figure the right amperage and so on to replace it.
Solar panels are made by cutting crystalline silicon into thin disks. Then dopants and metal conductors are spread across the surface. These disks are aligned on a solar panel making them ready for use.
What is a dead zone in sensors?
A dead zone in a sensor is the point where a sensor will not work. Ultrasonc sensors and specific optical sensors for example have measurement or detection ranges quoted as 30mm-300mm sensing. This means the sensor will not operate from 1-29mm or over 300mm.
You must have your foudation cubic feet per min first. Then using the thermistor measure the temperature and it should hold steady. The fluctuations in the resistance will show degradations in the airflow. More ohms the less airflow.
So Temp % resistance = x
Airflow =r
known computed airflow =f
ix= diff r/f
okay. i think i understand.
Where was the elevator first used?
An elevator by definition is a platform or an enclosure raised and lowered in a vertical shaft to transport people and freight. The shaft contains the operating equipment, motor, cables, and accessories.
Primitive elevators were in use as early as the 3rd century BC, operated by human, animal, or water wheel power. In 1743, a counter-weighted, man-powered, personal elevator was built for King Luis XV connecting his apartment in Versailles with that of his mistress, Madame de Chateauroux, whose quarters were one floor above King Luis.
19th Century ElevatorsFrom about the middle of the 19th century, elevators were powered, often steam-operated, and were used for conveying materials in factories, mines, and warehouses.In 1823, two architects Burton and Hormer built an "ascending room" as they called it, this crude elevator was used to lift paying tourists to a platform for a panorama view of London. In 1835, architects Frost and Stutt built the "Teagle", a belt-driven, counter-weighted, and steam-driven lift was developed in England.
Hydraulic CraneIn 1846, Sir William Armstrong introduced the hydraulic crane, and in the early 1870s, hydraulic machines began to replace the steam-powered elevator. The hydraulic elevator is supported by a heavy piston, moving in a cylinder, and operated by the water (or oil) pressure produced by pumps. Elisha OtisIn 1853, American inventor Elisha Otis demonstrated a freight elevator equipped with a safety device to prevent falling in case a supporting cable should break. This increased public confidence in such devices. In 1853, Elisha Otis established a company for manufacturing elevators and patented (1861) a steam elevator. While, Elisha Graves Otis did not actually invent the first elevator, he did invent the brake used in modern elevators, and his brakes made skyscrapers a practical reality.In 1857, Elisha Otis and the Otis Elevator Company began manufacturing passenger elevators. A steam-powered passenger elevator was installed by the Otis Brothers in a five-story department store owned by E.W Haughtwhat & Company of Manhattan. It was the first public elevator.
Why should kids have cell phones for emergency?
You've answered your own question, but it would be naive to imagine a child is going to confine his/her use to emergencies unless it's possible to have the 'phone call-barred to all but emergency or home/school numbers.
Looks like both are NiMH as NiCd batteries are generally not available for more than 800mAH rating. NiMH are common to have 1600mAH and more rating per AA cell. - Neeraj Sharma
"Ozone lamps" are UV light sources that use quartz sleeves between the environment and the mercury plasma that produces the light, and does not have the titanium dioxide coating that absorbs short wave UV and makes lots of visible light (the usual fluorescent light bulb does this). Normal glass will absorb too much of the UV. Ozone in the tropopause is produced by 215nm (or more energetic) UV light, and mercury vapor lamps produce some light at a more energetic 185nm wavelength.
It is the design of the part of something with which we interact to effect control of the work or outcome. Examples of the "something" are computers, appliances, machines, communication devices, etc. Examples of interfaces for these are keyboards/pads, touch sensitive panels, graphic layouts and icons (aka graphic interface), dashboards, etc. In this respect, the relationship of the question to photography is somewhat limited in that I believe most would consider a camera to have "controls" as opposed to an interface, so I have broadened the categories somewhat.

Where to find drive belts for old reel to reel tape players?
Parts for open reel tape decks are becoming harder to track down. While it is impossible to pick out a supplier that can help, here are some ideas to start a search.
First, as most open reel decks are professional equipment, start with search terms such as "Broadcast audio suppliers" or "professional audio" for example. Don't expect to find on line stores with stock of belts ready to be shipped. Once you have a few companies that at least look to be the right type, it's time to speak to them. Even if they don't have parts, you will eventually get passed on to just the right company. Expect to spend a few hours on the phone and you should get lucky.
How do you set nady ald800 frequency?
"Channel selection is controlled by DIP switches inside the transmitter. The system is preset at the factory. Changing the channel can be done quickly by any qualified service technician. See your dealer or the Nady Customer Service Department for detals." Remember that the receivers have to be retuned as well. This is from the product manual. There are 8 different frequencies that you can select from when you purchase the system.
Alternatively, you can manually retune the ALD-800 receivers by gently and slowly rotating the internal tuning potentiometer while close (ten to fifty feet away) from an active Nady, Drake, Williams, or similar transmitter broadcasting on one of the standard Assistive Listening Device frequencies. A non-metallic (plastic or fiberglass) tuning screwdriver (wand) should be used for this purpose. Tune for the center of best reception. This will probably void your warranty, but it is not rocket science. If you retune a receiver, be sure to remove the sticker indicating the old frequency, and replace it with a new sticker, preferably inside the battery cover.

Luigi (full name, Luigi Mario) is Mario's younger twin brother.
If you've played SSBB (Super Smash Bros. Brawl), you'll know who he is. He's mostly seen sporting a green L hat, white gloves, blue overalls, and a green long sleeved shirt. He's actually a coward since he's TERRIBLY FRIGHTENED OF BOOS. He's madly in love with Princess Daisy, and some people believe he is engaged to her.
Luigi usually wears green and has a better jumping ability however, his traction is lesser. In Super Paper Mario he was both an antagonist and protagonist. He was known as "Mr. L." Luigi is sometimes treated as lesser and is known to be timid and cowardly.
How do you fix bent audio jack for gaming headset?
About the only way to fix this is to replace the damaged part with a new one. This is probably not practical on a headset.
Radio, is the transmission and reception of electromagnetic waves.
It can also be the name given to the media industry that sprung up as a result of radio entertainment. e.g. "They got a job in radio".
The first practical means of using radio waves to communicate, was done by an Italian Gugliemo Marconi and he took out a British patent in 1897.
Who uses a screwdriver and insulating tape?
A screwdriver is a hand tool commonly used by technicians, engineers, mechanics, and DIY enthusiasts to drive screws into or out of various materials. Insulating tape, also known as electrical tape, is primarily used by electricians and technicians to insulate electrical wires and prevent short circuits or electrical shocks. The combination of a screwdriver and insulating tape is often used in electrical work to secure connections and ensure electrical safety.
How does geography affect industrialization?
Areas that have a good supply of minerals like coal have good steam industries. Places that are rich in cotton because of the specific rainfall conditions so they have a good textile industry.

How many milliamperes can humans typically tolerate before harm occurs?
It really depends on how much voltage is present in relation to the current; your physiogamy (heart condition, pacemakers, etc,) and how/where it is applied, age and your individual body resistance. Is it across the arms from voltage source to ground (one hand to the other) crossing through the chest? Is it a lightning strike?
A typical television's high voltage section runs at 15,734 hz. per second and generally ranges from an average of 19,500 to 23,000 volts. The average current available is seven milliamps, or .007 amps. Most people can handle a discharge from a TV, but it most likely will cause an adrenaline release in your body. Then, for about 45 minutes or so, you'll feel great. Then after that, you can expect a feeling of heavy fatigue as the adrenaline dissipates. I've been personally zapped several times over the years and that's about the only ill effects I've ever encountered.
ON the other hand, an electronic ignition coil can put out anywhere from approximately 35,000 to 100,000 volts at a much higher current. It too produces the same effect as a TV high voltage discharge, plus a numbing of the extremity inviolved.
Yet, we know too, that people have survived lightning strikes, and we're talking roughly a million volts at thousands of amps, and they too have survived the incident with little or no apparent damage (but not in all cases).
Having been burned by radio frequency from a ham transmitter running at 75 watts output, I encountered a very nasty little burn as I brushed up against the antenna with my thumb, which bore a perfectly round, 1/8" hole into my skin, cauterized the wound and left it complete with a scab to cover the hole. That was an especially nasty wound and it hurt for several days afterward, but I suffered no other ill effects.
It's possible place your hands on both terminals of a car battery at 12 volts, yet it has the storage capacity of a few hundred "cold cranking amps" and not feel a thing. Stick a 9 volt transistor radio battery to your tongue and you'll definitely feel a tingle, but on a "dead short" that same battery can deliver up to a whopping 80 amps for a fraction of a second.
How many milliamps? At what frequency? AC, pulsed DC or RF? At what voltage? For how long?
The whole point is that it varies from individual to individual and on many other conditions. Simple rule of thumb: Keep one hand in your pocket when working on anything where the potential to shock you is present, and don't believe "trueisms" concerning electricity.
What is the effects of corrosion on the computer system?
Corrosion can cause the main hardware parts to malfunction or simply stop operating. Corrosion on the power supply unit can cause short circuits and fires.
A battery containing five 2V cells connected in series has a total voltage of?
10 volts.
The formula to work that out is:
quantity of cells*voltage of cells
What is the difference between UK electricity and eu electricity supply?
UK and European electricity supplies now conform to a single standard of 230VAC at 50Hz. This is a recent change from the UK voltage of 240VAC and mainland Europe of 220VAC.
Mains outlets are different. The UK uses a square, three pin plug that has a fuse built into the plug body. The fuse is normally 3, 5, 10 or 13A. Mainland Europe uses a round, two pin plug with the earth pin either protruding from the socket or two blades that connect with the outside of the plug. European plugs are not fused. Adaptors are freely available to convert between European and UK connections.
Although this is a Europe wide standard, some of the more remote and rural countries have less than perfect supplies. In some of the Eastern Block countries, voltages have been known to drop to under 160VAC at times. While many electrical devices will operate at the reduced voltages, others will fail as the voltage drops. For travellers who are visiting some of the far reaches of Europe, it might be worth checking the typical voltages before assuming that equipment will operate.
CommentThe so-called 'change' from a nominal voltage of 240 V to '230 V' is simply a paper exercise, to satisfy the EU's obsession with standardisation. In practice, there has been no change whatsoever to the actual nominal voltage. The original standard specified 240 V +/- 6%, and this remains the current situation. However, the new standard 'specifies' 230 V +10%/-6% and, although this appears throughout the new Wiring Regulations simply to comply with the EU requirement. Once again, a completely wasteful exercise hoisted on the UK by the EU!What will happen if you give DC input to the primary of a transformers?
If DC voltage is applied to the primary of a transformer the flux produced in the transformer core will not vary but remain constant in magnitude therefore no emf will be induced in the secondary winding except at the time of switching on.Also there will be no self induced emf in the primary winding to oppose the applied voltage and since the resistance of the primary winding is quite low heavy current will flow through it which may result in burning out of primary winding.
