Does an orange make a better battery than a potato?
i dont know some one outside of me please improve this answer it is for my science project
As this is for a science project, it would be wrong to simply give one answer. In fact, there are several things to test when deciding which is the best fruit or vegetable for a battery.
First, take a potato and an orange. Use different types of electrodes - try to get hold of steel, copper, zinc and aluminum. With each pair of electrodes, measure the voltage they produce. Then measure the current they produce. Finally, measure how long each one will operate.
Put the results into a table and then you are well placed to make your own evaluation of the data. The experiments won't take long to do and following the guide above, you will have enough information to get a real answer.
How does coating with plastic help prevent rust?
It prevents oxygen and moisture from combining on the metal which would create rust.
What condition are necessary for a current to be present in a circuit?
The only two things needed for current flow are electromotive force or voltage and a conductor. The amount of current flow will depend on the "Resistance" in the circuit.
A method of burning coal as a fuel in making iron was developed in the 1830's. Demand for iron in manufacturing was very high. As American industry became able to make it's own iron, industries that made machines, farm tools, rails, and parts of railroad cars grew very quickly.
What was the name of the first website?
Depends on your definitions of "public" and "website," but the first one was probably the World Wide Web Consortium's World Wide Web Project's start page.
Here's a copy: http://www.w3.org/History/19921103-hypertext/hypertext/WWW/TheProject.html
How much songs can hold in 160gb?
Of course, this all depends on:
1) How compressed the file is (Bitrate)
2) How long the song is (Seconds)
3) Compression codec used
4) Ultimately, this translates to what is the average file size (in MB) of the songs.
So... there are 1024 MB in a GB, so 1024 * 160 MB in 160 GB or 163,840 MB in 160 GB.
If the songs are of an average file size of 4 MB then 160 GB would store 40,960 songs.
Sony does make a very nice plasma t.v yet there are other brands that are just as good such as Samsung and Panasonic.
CDs are a popular way to store and transport information and pictures. Users who are trying to determine how much room a disc contains will find a CD holds over five billion bits.
How do you program a Regency TS-1 Scanner?

How do you turn off the alarm on a g-shock wrist watch?
The best way I think is to press these 2 buttons. Start and reset.
Can you play digital 8mm tape on analog camcorder that records on 8mm or Hi8?
The question here reads, can you play a Digital 8mm tape on an analog camcorder. The answer to this is NO. An analogue Video8 or Hi8 camcorder will display nothing useful if playing a tape recorded with the Digital8 standard.
Only a Digital8 camcorder can play a Digital8 recording. In many cases (but certainly not all) such a Digital8 camcorder will also play analogue Video8 and Hi8 tapes.
Be aware that sometimes a person will have used a tape branded as Digital8 to make recordings with a Video8 or Hi8 camcorder, and in this case the recordings ARE analogue.
Another option is to convert your 8mm tapes to digital or DVDs. There are a lot of 8mm video transfer services out there that can do this for cheap. StashSpace.Com is a good one, costs $6.95 per tape and they let you watch and edit online for free. Outside USA, try a Google search for "digital8 to DVD transfers UK" or similar.
What is the pros and cons of simulation technology?
Simulations can be used to explore and gain new insights into new technology, and to estimate the performance of systems too complex for analytical solutions.
Disadvantage, it is only a simulation, and the results could vary greatly in the real world due to unforeseen factors.
Facts on Why electronic device should be allowed in school?
Cell phones make cheating easy. Text messaging to get answers and cell phones with Internet access to look up data gives students a quiet way to cheat. It is more difficult to prove that a student used his cell phone to cheat, so many schools prohibit phones in class.
DistractionCell phones that beep or ring create unnecessary distractions from teaching time in class. Laptops allow students to get online during class, which creates distractions for them and the students around them. MP3 players provide another distraction for students.
BullyingCyber-bullying, which occurs with the use of the Internet, is easier to get away with and more difficult to control when students are allowed to bring cell phones or laptops to class. Online bullying is just as damaging to students as physical bullying, and electronics facilitate this kind of harassment.
Classroom InteractionElectronic devices give students an excuse to refrain from participating in class discussions and interactions. Removing laptops and cell phones from the classroom creates an atmosphere in which students and teachers can communicate without electronic competition.
What is the difference between a refrigerator and a freezer?
An ice box is literally what it says it is, a box that has ice in it. The ice kept the food cool and it had to be replaced on a regular basis, usually daily. A refrigerator uses a compressor and gas cycle to keep the contents cold.
What are the main components in the processor?
The Central Processing Unit/Processor: A CPU is also called the processor and it is the main component of the computer. CPU is the brain of the computer and provides ability to computer for executing any given instruction and also tells the computer how to control the flow of instructions. In a computer system, all major calculations and comparisons are made inside the CPU and the CPU is also responsible for activating and controlling the operations of other units of a computer system. The quality of CPU inside a computer determines the quality of the computer.
Basic Parts of a processor: A CPU has the following main parts:
ALU (Arithmetic and Logical unit): This unit of the CPU is capable of performing arithmetic and logical operations. This unit of the CPU gets data from the computer memory and perform arithmetic and logical operations on it. The arithmetic unit of ALU performs arithmetic operations like addition, multiplication, subtraction and division. The Logical unit of ALU performs logical operations such as comparison of two numbers. It tells us which number is greater and which is smaller. The common comparisons such as less than, equal to, or greater than are performed by the logical unit.
Memory Unit: A processor has its own memory inside it in the shape of small cells. Each memory cell is called a "Register". Registers are used to carry data temporarily for performing operations. There are total 13 registers in a processor. ALU gets data from registers and stores it in registers to perform arithmetic and logical operations. And data comes in registers from main memory of the computer.
Control Unit: This unit of the processor controls all the activities of the processor and also controls the input and output devices of the computer. It acts just like a police inspector who controls the traffic on a road. The control unit controls the whole traffic of the computer. It tells the input device that it is now his turn to feed data in the computer and show result of data after execution on the output units. This unit also controls the flow of instructions, which are given to a computer. It obtains instructions from the program stored in main memory, interprets (translation of instructions into computer language) the instructions, and issues signals that cause other units of the computer to execute them.
What is the difference between a wet cell and a dry cell?
* A "dry-cell" battery is essentially comprised of a metal electrode or graphite rod (elemental carbon) surrounded by a moist electrolyte paste enclosed in a metal cylinder as shown below. * In the most common type of dry cell battery, the cathode is composed of a form of elemental carbon called graphite, which serves as a solid support for the reduction half-reaction. * At the center of each dry cell battery is a rod called a cathode, which is generally made of metal or graphite and is surrounded by an electrolyte paste. The cathode and electrolyte paste are wrapped in paper or cardboard.

Will 9v 1100mA power adapter work with your 9v 500mA device?
Yes, a 9v 1100mA power adapter work with your 9v 500mA device. The mA number is the maximum amount of amperage that the adapter will produce without overloading itself. At 500 mA the adapter will only be working at half load.
