What fruit produces the most electricity?
Fruits and vegetables as such does not actually produce electricity.
They do however poduce various acids.
These acids can and will together with various metals make it possible to shift electrons from one metal to another.
Metals can not be the same. Metals like Copper, Silver and Zinc work very well. Preferably Copper and Zinc, or Silver and Zinc. Copper and Silver works too, but produces lower voltage.
It is the electrons flowing from one metal to another via the acid that makes the electricity.
Note:
many factors determine the actual voltage and the current possible to drain from your home-made battery.
The current is dependent on the contact surface of your chosen metals. Very large surface can make a large current. Small surface makes a small curent.
The voltage is dependent on how many fruit 'batteries' you connect in series. you may get between 0.2 and 2 volt per fruit, depending on metal and how acidic the fruit is. Citrus fruits like lemon is very suitable.
Warning:
Do not eat the fruit afterwards as they will contain a dissolved solution of metals. That may be harmfull.
What is the mass of a CD player in grams?
The Samsung SH-D162D/BEBE which will play CD's and DVD's weighs 750 grams. This is for mounting in a computer chassis. A standalone unit will weigh at least double that.
What forms of electricity are there?
The two forms of electricity are Alternating Current (AC) and Direct Current (DC).

What is wrong with your home AC that has freon but is not blowing cold air?
Check the AC fuses. There's usually two sets. One at the electrical box and another set at the compressor in a wall mounted box. There may be two of them and one of them blew out. The other possibility is that the compressor/fan motor start capacitor is bad. Sounds like the furnace fan is running but the compressor isn't.
Other item to check is to make sure that you have the thermostat actually set on AC. A lot of times people will flip the switch thinking they're turning the AC on only to find out they just turned on the fan switch.
How can a microwave oven hurt you?
Sadly yes, a microwaved egg works as timed bomb, after certain processes happen inside the egg it explodes, often after being removed from the microwave. There has been eye operations following pieces of egg hurting eyes. Metal in the microwave can cause fire, so better be careful.

Microwaves, even in small doses, can affect living skin cells.
You must check that the door seals are intact and do not leak microwaves out. You can buy microwave detectors to check for your self or take it into a repair shop for servicing.
Make sure that the interlocks work, the oven should not work with the door open.
Do not stand close to the door at face level when it is cooking. Microwaves leaking from the door can cause cataracts of the eyes.
Equation for voltage in a parallel circuit?
You can measure across *any* component - see the answer on measuring voltage.
For any resistance measurement, be SURE that:
1. The circuit is disconnected from the power supply, and
2. "Energy storage" components such as capacitors are discharged.
If the circuit does contain capacitors of reasonable size (microfarads or more) these may demand some power from the meter to charge them, so you can get an artificially low reading at first, but it will rise to the correct value as the capacitors charge.
A robot is designed to automatically or remotely manipulate an object or objects by mimicking a human movement. The robot is either built to be stronger, less susceptible to damage, steadier, or built to withstand tedious repetition.
In simple terms a machine has moving parts that redirects energy like a car or pinball game. A robot is a specific type of machine designed to manipulate its environment on its own. Machines should not be confused with electronics like computers which have no moving parts but in common usage are considered machines because electronics often have internal machinery and vice versa.
What is a car battery made of?
It is made of a plastic case, in which there are 6 compartments, inside each there are several plates made of a frame covered with a lead-based paste. These sit in an acid bath, which works with the plates to make a chemical reaction which makes the battery volts.
Yes it can. However, it will only evolve when you teach it the move double hit. Then it will elvove into ampipom, which has two fists for tails, i.e. DOUBLE HIT..
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.

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.
