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

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.

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

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.

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.

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 %).

85 decibels maximum.

Well you mean "when was iron found "not "when was iron invented" People dugged it up 5000 thousand years ago from now.Iron - or the discovery of how to make iron was - unlike other metals - was done by the Hittites who came from c. Turkey / northern Mesopotamia. As far as scientists / archaeologists can determine the discovery of iron happened only once in human history unlike copper or bronze. This may seem unlikely but given the fact that metal working as a whole was unknown (generally accepted to be the case) at all in the American continents, then only one origin for iron working itself is not unreasonable. Given that humans lived in the Americas for 15,000 years but did not work metal suggests that the discovery / ability to work metal (of what every sort) was something that happened rarely in human history and was not something that was 'bound' to happen. The surprise perhaps is that metal working was ever discovered ....

A computer is not a robot. Many robots will have different types of computers in them to help them operate properly, i.e. in car manufacturing.

The typical estimated life of a Lithium-Ion battery is about two to three years or 300 to 500 charge cycles, whichever occurs first. One charge cycle is a period of use from fully charged, to fully discharged, and fully recharged again. Use a two to three year life expectancy for batteries that do not run through complete charge cycles.

Rechargeable Lithium-Ion batteries have a limited life and will gradually lose their capacity to hold a charge. This loss of capacity (aging) is irreversible. As the battery loses capacity, the length of time it will power the product (run time) decreases.

Electric current, but the voltage required depends on the electrical standards of the country you are in.

So when you're on the toilet people can't see you.

No they are not real they are just animated with effects.

A half century or fifty years

Negative ions have an excess of electrons while positive ions have a deficiency of electrons.

it was invented by Alexandre Godefy in 1890 in France.

Current symbol I =voltage/resesistance I=V/R for direct current (dc) and for a resistive load in alternating current (ac)

Variable resistor is an resistor that can change its resistance manually, by rotating a handle or a screw.
