Which is a common characteristic of both nuclear and conventional electric power plants?
They both use a conventional steam turbine/generator, with a steam circuit that operates on the Rankine cycle (look it up in Wikipedia). This applies particularly to coal fired stations, many natural gas plants now use combustion turbines combined with using the exhaust heat for district heating, but these could be excluded from being 'conventional'.
How do you program garage door opener in Lincoln town car 2004?
Not sure if it's the same as the 1996 Jeep, but here are it's instructions.
It's pretty easy. To help clarify I'm going to number the buttons 1, 2, and 3 where 1 is the button on the outside, close to the door, and 3 is the button on the inside.
Setting a button:
1.) Hold down the desired button and the LED will start to flash slowly (if it is solid this means that it has already been programmed and you must do a reset to program or select a different button).
2.) Continue to hold the desired button and then hold the garage door opener close to the visor and hold down it's button. You know the visor is programmed when it changes from a slow flash to a fast one.
3.) Release the buttons and test it out.
*** For rolling code garage door openers follow additional steps below***
After you have trained the jeep remote as stated above, you will notice pressing the button you have programed does nothing if you have a rolling code garage door opener.
4.) Press the learn button on your garage door opener (usually only have 30 seconds) and run back to the car and hold the button you programed for 2 seconds and then release. Now, repeat the "press/hold/release" sequence a second time, and, depending on the brand of the garage door opener (or other rolling code equipped device), repeat this sequence a third time to complete the programming.
Resetting the visor controls:
1.) Hold down buttons 1 and 3, for about 15 seconds, until the red LED starts to flash. Remember that this will reset all 3 buttons.
Hope this helps.

Does a D cell battery have more voltage than an A cell battery?
this question is missing information and therefor makes no sense
There are many possible ways to chat on the iPad. Two of the most popular IM client is BeejiveIM for iPad and IM+ Pro. Both provide native looking interface and are very user-friendly.
Any other websites that provide a chat system may also work on the iPad mobile safari browser. From my experience, Google Chat and Facebook Chat work with a little lag.
Cheers

What is the purpose of the grading system?
A second objection to norm-referenced grading is that it promotes competition rather than cooperation. When students are pitted against each other for the few As to be given out, they're less likely to be helpful to each other.
Possible ModificationWhen using a norm-referenced system in a small class, you need to modify the allocation of grades based on the caliber of students in the class. One method of modifying a norm-referenced system is anchoring. Jacobs and Chase in Developing and Using Tests Effectively: A Guide for Faculty, 1992, describe the following ways to use an anchor:"If instructors have taught a class several times and have used the same or an equivalent exam, then the distribution of test scores accumulated over many classes can serve as the anchor. The present class is compared with this cumulative distribution to judge the ability level of the group and the appropriate allocation of grades. Anchoring also works well in multi-section courses where the same text, same syllabus, and same examinations are used. The common examination can be used to reveal whether and how the class groups differ in achievement, and the grade in the individual sections can be adjusted accordingly.... If an instructor is teaching a class for the first time and has no other scores for comparison, a relevant and well-constructed teacher-made pretest may be used as an anchor."
Modifying the norm-referenced system by anchoring also helps mitigate feelings of competition among students since they may feel they are not directly in competition with each other.
Before deciding on a norm-referenced system, consider:
- What is your expected class size? If your class size is smaller than 40, do not use a norm-referenced system unless you use anchoring to modify it.
- Is it important for students to work cooperatively in this class (e.g., do you ask them to form study groups or work on projects as a group)? If the answer is yes, a norm-referenced system is not appropriate for your class.
In criterion-referenced systems students are evaluated against an absolute scale, normally a set number of points or a percentage of the total (e.g., 95-100 = A, 88-94 = B, etc.). Since the standard in this grading system is absolute, it is possible that all students could get As or all students could get Ds.
AdvantagesStudents are not competing with each other and are thus more likely to actively help each other learn. A student's grade is not influenced by the caliber of the class. DisadvantagesIt is difficult to set a reasonable standard for students without a fair amount of teaching experience. Most experienced faculty set criteria based on their knowledge of how students usually perform; thus, criterion-referenced systems often become fairly similar to norm-referenced systems. Possible modificationsInstructors sometimes choose to maintain some flexibility in their grading system by telling the class in advance that the threshold for grades may be lowered if it seems appropriate. Thus, if a first exam was more difficult for students than the instructor imagined, s/he can lower the grading criteria rather than trying to compensate for the difficulty of the first exam with an easier second exam. Raising the criteria because too many students achieved As, however, is never advisable.Another way of doing criterion-referenced grading is by listing class objectives and assigning grades based on the extent to which the student achieved them. (For example, A = Student has achieved all major and minor objectives of the course; B = Student has achieved all major objectives and several minor objectives; etc.).
Before deciding on a criterion-referenced system, consider:
- How will you determine reasonable criteria for students? If you are teaching the class for the first time, it is advisable to maintain some flexibility.
In contract grading instructors list activities students can participate in or objectives they can achieve, usually attaching a specified number of points for each activity (e.g., book report = 30 points, term paper = 60 points). Students select the activities and/or objectives which will give them the grade they want and a contract is signed. It is advisable to have qualitative criteria stated in the contract in addition to listing the activities.
In some classes, a portion of a student's grade is determined by peers' evaluation of his/her performance. If students are told what to look for and how to grade, they generally can do a good job. The agreement between peer and instructor rating is about 80%. Peer grading is often used in composition classes and speech classes. If used, it should always be done anonymously.
Students can also be asked to assess their own work in the class and their assessment can be a portion of the final grade. This method has educational value since learning to assess one's own progress contributes to the university's goal of preparing students to be life-long learners.
A research analysis found that the percentages of self-assessors whose grades agree with those of faculty graders vary from 33% to 99%. Experienced students tend to rate themselves similarly to faculty while less experienced students generally give themselves higher grades than a faculty grader. Students in science classes also produced self-assessments which closely matched faculty assessment. If self-assessment is used, the instructor and student should meet to discuss the student's achievement before the self-evaluation is made.
50 mA generally stands for 50 milliamperes.
A milliampere is a measure used for small electrical currents.
What is the main function of a modern television receiver?
Entertainment mostly. Sometimes, if you get a good filmmaker, they could use their movie to send a message. But, about 90% of the time, it is just to show off someones directing or acting skills.
------------------------
To tell stories. There is a deep-seeded human need for storytelling. Some anthropologists theorize that it aids in the development of higher brain functions. Movies represent the modern method of telling a good story around a fire, with your friends, having something to eat and sharing a common experience - just like our cave-dwelling ancestors used to do.

Why is it not safe to have a radio next to the tub while you are taking a bath?
DO NOT USE ANYTHING CONNECTED TO MAINS ELECTRICITY IN THE BATHROOM. This includes anything connected to the mains via a low voltage power supply. However, a radio powered only by its own batteries should not hurt you, although the radio may be seriously damaged by water or steam.
The original purpose of air conditioning is the same as it's purpose today, which is to keep people and animals cool. Without air conditioning, the population of many Southern states would be much smaller.
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.

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.

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.
