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.
How can technology companies help to alleviate the problem of technology overload?
I don't think that it is possible
How do you connect an external hard drive to your computer?
The only way you can do that is to buy any external HD case that has either a firewire or USB interface on the back. Install the HD in the case and use one of the two interfaces I mentioned to connect it to your laptop.
you get a external plug it in by the cable that is provided into the usb of fire wire por on your pc/mac
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.
Why do parents buy teens cell phones?
If used responsibly it is a wonderful source of information. Imagine when you were a child and a thousand questions came into your head a day. How does this work? Where does electricity come from? etc. By the time you got home you had forgotten all about it. But imagine you could find out the answers on the spot or when you were sitting on the bus or waiting for a lift. It is a wonderful educational opportunity. It just needs to be carefully monitored and ground rules need to be set as with any other form of ICT.
Basically because the parents just give in to their children when they keep on nagging them about getting them a smart phone.
Terrestrial microwave technologies share with satellite microwave technologies many of the scientific and technical improvements used to accomplish microwave transmissions. They are different in that satellite microwave technolgies seek to neutralize the effects of the atmosphere in the microwave transmissions. On the other hand, terrestrial micowave technologies seek the aid of atmospheric effects on microwaves to extend the range limitations imposed by the Earth's curvature. Examples of these terrestrial technologies include those used to exploit troposcattering and meteor-burst in microwave communications--not used at all in satellites. Professor Martinez
Where was the first cell phone created?
In 1947 Bell labs made the first cell phone, but in 1973 Dr. Martin Cooper took it further and made the cell phone like the ones we have today. He worked for Motorola. It was in 1983 that the first cell phones were offered for sale to the public.
How do you use an electronic whiteboard?
An interactive "smart" white-board with "electronic ink" and touch-sensitive screen can be hooked up to a computer and a projector. The board magnifies images clearly and colorfully. The board has annotation capabilities
How do you clean a garbage disposal?
The easiest method to use is to pour 1/2 c. baking soda down the drain and follow it with 1c. of white vinegar. Let it set for several minutes while you boil some water. Pour the boiling water down the drain and flush the drain throuroughly. This is the method I use most often and it works well to clean it, get rid of smells and get it running more smoothly again. If you have a double sink you should clean both drains. Another method is to put a tablespoon of bleach in a gallon of water, pour it down the drain, let it sit for several minutes and flush the drain with cold water. I don't think this works nearly as well. You can also use ice cubes and citrus rinds to help clean the blades and the citrus rinds will give you a nice, fresh scent.
How well does copper conduct heat?
The thermal conductivity of copper is 401 W·m−1·K−1 (watts per meter Kelvin). Which makes it one of the most conductive elements.
Power source for portable CD player?
either double aa baterries or the plug in charger (if recieved). Hi I have posted a link to a website that sells portable power packs for electronic devices, I have a PowerGorilla that I use to power my laptop for a further 5 hours so I can work in the garden :) The PowerGorilla will also power a DVD player because I use it on the plane when I fly to the UK, the DVD player we have doesn't last long enough, hope this helps
800watts RMS is 5,000,000,000watts PMPO. However, if you upgrade to the high viscosity audio cable, you can get as much as 8,000,000,000watts PMPO.
Now, for the series answer.
PMPO has no grounds in science, and you will never find it in any legitimate engineering text. It is a made up value to exaggerate the capability of the audio system for marketing purpose only. So, you are free to make up whatever conversion you want to calculate the PMPO.
Any legitimate audio manufacture will not advertise using PMPO, even the use of Peak Power is iffy. Stay away from any audio equipment advertising PMPO.
For the power value to have any meaning, the manufacture needs to indicate both the power (in watts) and the distortion (in %).
How much money is a model B kodascope projector worth?
Depending on the condition of the mechanics of the machine, as well as the cosmetic appearance of the machine, a range of $50.00 to $300.00 would be the going price. I have seen this item at a thrift shop for $27.00 intact. Although this is a rare find, over the years I have seen them at yard sales and pawn shops as well. Replacement bulbs and tubes are sometimes problematic. If you happen to locate a machine that is up and running when you buy it, you run the risk of blowing a bulb or tube each time the machine is switched on. The hardest thing a tube has to do is turn on. The initial power surge is usually what kills the tube. When I was in the military, we had lots of tube powered electronic devices, which we never switched off. This extended the life of the tubes for years as opposed to weeks when switching off/on. Of course you can't leave your projector on for this amount of time, I include this information about tube technology as most folks today do not have experience with tube devices. A few Fender Guitar Amps still use tubes, as the sound is preferable to transistor amps. Tubes were last manufactured in China, after the USA companies discontinued production. A quick internet search for bulbs and tubes might be in order before investing in a projector that you intend to operate on a long term basis. These machines are great fun and as a kid inspired me to going in to the motion picture business.
To me the Kodacope Projector is priceless!
