what i mean is when you stay outside a long time in the cold and come inside, your hands have a burning sensation.

Optic mice have a simple red LED that shines downwards, along with a small little camera that tracks changes in the reflection off the surface. Special chips in the mouse detect which direction the mouse moved and report this back to the computer. The concept is simple, but the programming is a bit complicated.

The burning sensation might just be caused by your hands warming up, thereby triggering the two sensors, like I said earlier.

It sounds more like your nerves had become numbed and as they are warming up, the sensation of them just starting to warm up feels like burning.

how high does a helium balloon go up? i say it could go into space, but my friend says it would loose helium by then, but helium expands as it goes up, so it would replace the lost helium?

The higher up the balloon goes, the colder it gets, and when the temperature or something goes down, so does the volume of the balloon goes down. This is according to Charle's Law where Original Volume/Original Temperature=Volume2/Temperature2

Balloons filled with helium float because the air density inside the balloon is much less than the air density outside the balloon. The balloon will rise until the density on both the exterior and the interior of the balloon are equal. Note how this assumes a perfect balloon, with no changes in the helium. In actuality, the pressure, volume, and temperature of the helium changes due to the change in air temperature and density. There's no simple way to model this behavior. Also, no balloon is perfect, so some helium leaks out.

Charles' Law is simply a specific version of the universal gas law:

PV = nRT

This means that the product of the pressure and the volume of the gas is equal to the product of the number of moles of the gas, the universal gas constant, and the temperature. Since the number of moles of the gas doesn't change, and neither does the constant (If it did, we'd be screwed), we can say that:

P1 * V1 / T1 = P2 * V2 / T2

We're allowed to equate these two to each other since they both equal n * R.

Using that equation, we can normally predict how a gas will act, but in this case, there's too many changes to accurately predit how the helium will react.

how does closed captioning work?

For those who don't know, CC (closed captioning) is a system of printing out spoken words on the television for those who are hard-of-hearing or deaf. CC information is sent as channel 1 (in the US) or another special channel in other countries. This explains why you can never get to channel 1. By the way, this only works on broadcast systems, like antenna or cable. Satelite television transmits CC information in a proprietary format dictated by each carrier. Televisions listen to channel 1 for the lines of text to display for each of the other channels.

Every Member of my family gives a different answer, so I ask you. If I make an internet game, and I use the sprites of another proper, (one sold for game bay Advance), can I get sued?

Nope. Although the sprites that you're using are copyrighted pieces of material by the game company, you're allowed to use them in that manner under the Fair Use Law (Title 17). Source: http://www4.law.cornell.edu/uscode/17/index.html

the mystery of channel 1 explained. how come when i browse through some of the high number channels (our egular cable channels are in a range from 2-36) sometimes on channels theres something on, like channel 7 only real staticy

How does the hive mentality of insects work? Like, bees and ants. Is it anything like the Buggers from Ender's Game?

Sorry about the long delay. I had planned to answer these a little while ago, but for some reason I forgot about the questions.

Static on radio and televison is caused by the same thing: interfering signals. In broadcast, the interfering signals are other sources of radio and television waves, such as other radio or TV stations, or just large sources of energy. The interfering signals in a cable line come from those same large sources of energy, like power plants, plus random magnetic fields pass through the wire. This doesn't affect every channel, as each channel is put on a different frequency, and the interfering signals only affect certain frequencies.

Nope. Nothing like the Buggers, as far as we can tell. Mostly, it seems that the "hive mind" effect of insects comes from the ability for one organism, usually the queen, to control the rest through a method of releasing pheremones into the air. The other drones of the colony "smell" the pheremones and interpret them into instructions. The insects also communicate with each other to pass along data, like bees dancing to indicate the location of a source of nectar. All of these combined create the illusion that all of the insects are of one mind.
