What happens when you roast salt with a magnifiying glass?
It will get very hot before it melts. At first, the salt particles may jump about and crackle as water (which may be trapped within the crystals) boils off. In time, if the heat source is sufficiently intense, the salt will melt and become a clear liquid.
Salt (NaCl) melts at 801C (1474 F) and boils at 1465 C (2669 F).
It would take quite a magnifiying glass to get it that hot so my guess is that you might get it to melt.
What is the difference between potential difference and electromotive force?
They are very similar, but there is one key difference.
Both represent the change in energy (per unit charge) that a charged particle would experience if moving between two points.
The difference is that a potential difference usually refers to a static situation. In this case, if a charged particle moved from Point A and returned to Point A, the change in potential would be zero.
An EMF usually refers to a dynamic situation within a circuit -- ie, a looping conductor. In this case, a charge that went around such a circuit and ended up at its beginning point, would actually experience a change in energy.
The 15 organ systems in your body?
There aren't really 15. Some of them that I researched are the same thing as another one. Here are all the body systems.
1. Respiratory (Pulmonary) System
2. Circulatory (Cardiovascular) System
3. The Skeletal System
4. The Muscular System
5. The Digestive System
6. The Integumentary System
7. The Nervous System
8. The Immune System
9. The Lymphatic System
10. The Endocrine System
11. The Urinary (Excretory) System
12. The Reproductive System
How much would you get for a ps1?
Less than 20 dollars in most places here in the states, maybe a little bit more elsewhere.
As classic as this system is it's also over 14 years old and many of the more popular titles are becoming available on the PlayStation Network. My advice would be to hold onto it for the sake of nostalgia.
How do you get the azure fluet?
The Azure Flute hasn't been officially distributed yet. The only way of getting it is via cheating with an Action Replay DS. Arceus has been distributed at Toys R Us before and given out at the 12th Pokémon movie in Japan. It is otherwise unobtainable at this point.
What happens to an electric current at a light switch?
When an electrical switch is in the off position, the circuit is interrupted. When the switch is on, the circuit is open and complete.
How can you have two televisions on the same recEIVER and watch different channels?
Actualy each recivers recives ' n' no. of channels. so the channel that u wants to view can be selected by the T.V. not by the Reciver. So we can view 2 different channels in 2 diffrent T.V with only 1 reciver.
I know it is about light and dark and about how it is used in the picture. hope this helps !
Is a sky cable a cord which is at least 3 ft long?
A sky cable cord does have a cord that is at least three feet long. In fact the cable cord lengths can very. they can reach up to eight feet long, which is alot in terms of cable cords.
What Year the Digital TV Will Start?
Digital TV has already started. Many TV stations are now broadcasting in digital formats throughout the country.
However, the `official start time' is February 17th., 2009. That's when the TV stations may turn off their analog signals entirely at their discretion.
Want a set top converter box for your analog TV? How about a $40.00 off coupon? Go to: www.dtv2009.gov. (or call: 888.dtv.2009) They've got about 890 million dollars worth of coupons to give away on a first come, first served basis. Since most of them will probably cost close to $40.00 each, you might just have to add a few bcuks if you want something fancier.
I would say that he is because; Akuma never had Satsui No Hadou At birth but when akuma trained under goutetsu he gained his Evil power. And that proves that not only can Satsui No Hadou be gained through fighting style, but through bloodline as well; this is why I think Akuma is Ryu's biological father; If you see the alpha generations movie you will see that ryu looks like akuma at a young age; there is also similarties between them in game.
Where do you find a lead screw?
A lead screw is known as a power screw or translation screw, is a screw designed to translate radial motion into linear motion. They find their use in machine slides (such as in Lathe machines), Vices, Screw Presses, and Jacks etc.
For more thrust applications, you require a larger diameter screw . That's because the screw is similar to a column subject to compression and tension. During compression, the screw should not bow or deflect. And during tension, the screw must support the load without failing.

How do you wire a speaker volume control?
This is strictly dependent of the type of control being used. If you just have a potentiometer (variable rotary resistor) then connect ONE wire from the source to the middle (wiper) terminal on the Pot. then from either other terminal on the Pot. continue the circuit to the speaker.
This just limits the amount of signal going to one speaker. THIS IS ONLY APPLICABLE WHEN ONE SPEAKER IS USED. If you could direct me to the instructions that came with your controller, I could help you out.
See my Bio.
If you purchased this from a Radio Shack, or similar electronics supplier, tell me the part, model number and I look it up for you.
ABOVE ANSWER IS TOO SIMPLISTIC....
Speaker volume control, done properly, is not a matter of just adding resistance (or variable resistance) to the line. Properly done, the amplifier's output impedence must be matched to maintain proper loading and avoid premature burnout and distortion.
Dynamic speaker connections (2, 4, 8 ohm, for example) can have a volume control added by using a potentionmeter (variable resistor) with decent results and without doing damage or getting too much distortion. For most applications this is okay.
What you need for a simple resistance control:
A 2-gang potentiometer of about 15 to 25 ohms rating. Here's more than you'll ever need to know: http://beavishifi.com/articles/Volume_Control/index.htm
THE RIGHT WAY:
The right way to do this is to use an 'impedence matching' control. These controls allow you to put on strings of speakers yet maintain a constant impedence to the amplifier output (up to the power limit of the amp, of course).
Here, now, is what you need: http://www.audioc.com/accessories1/misc/vcontrol.htm
ANOTHER WAY:
There is another way to do all this.. that is if you have pro-grade amps. You can use what is called 70volt lines. 70volt amp outputs allow you to string many speakers down the line (each with its own step down transformer, not hard to wire or figure out). If this is of interest then you may want to Google it and go from there.
HOPE THIS HELPS.. Caio!
