What is precision and accurancy?
Precision is how to keep track of good a measuring device is. Accuracy is how close an answer is to being correct. Something can be precise but not accurate. Something can be accurate but not precise.
What is the resultant of a group of vectors if drawing them tip to tail produces close figures?
The result is a zero vector. If the sum of the vectors forms a closed figure, the vectors sum to zero.
What is the definition of Motion Detector?
yuyiuyiouyoiuyANS 2 - it's an electronic device that detects movement within a certain close area, and usually sends it's signal to a light illuminating the area.
Where does wave energy have to be sited?
Wave energy can be harnessed in coastal areas, close to the shore. There has been one such device working on the island of Islay in Scotland since the early 1990s, producing 75kW of electricity.
How many different colors are there in light and what are they?
That's like asking "How many different lengths are there on a ruler, and what are they ?" There are an infinite number of colors in light. Conceptually, every different wavelength/frequency is a different "color", although your eye may not have the resolution required to separate two colors if their wavelengths are too close together. Whatever two wavelengths you name in the visible range, no matter how close together they are, I can always name another wavelength ... or a million of them ... that fit in between your two. The number of colors there are in light is equal to the number of colors that school kids name in the rainbow, plus the number of paint colors that Sherwin- Williams can mix for you, plus the number of fabric, drapery, and carpet swatches there ever were, plus another infinite number more in addition to those.
What is a device used to open and close an electric circuit?
The device is called a switch.
What country produces the most meat?
China produces the most with the U.S.A in a close second
How does a electrostatic precipator work?
an electrostatic precipitator is a device in which a dusty air stream is passed through some plates carrying a high voltage. This adds an electric charge to the dust particles. When the air stream then passes close to some plates that are grounded, then the charges attract the dust to the plates, and the dust is captured for disposal.Some furnace processes create a lot of fly ash, and the above device is typically used to capture the dust.
Produces measurements that are close to one another?
Estimation
Do you measure photons energy with wavelengths?
you see how close the wavelengths are-- the closer, the more powerful it is. Here are the wavelengths- from least powerful to most powerful: Radiowaves, Microwaves, Infared Waves, Visable Light, Ultraviolet, X-rays, and Gamma rays.
Why do the places close to the sea experience moderate climate?
gulf stream
What produces measurement that are close to one another?
accuracy
What are the wavelengths of the electromagnetic spectrum?
Effectively from zero to infinity, although neither of those two values are valid. But you can get as close to them as you want.
What device will open or close the break in a electrical circuit?
A switch.
When a plastic comb is rubbed with a piece of animal fur and is brought close to a fine stream of water from a tap the stream of water will be?
The stream of water will be altered by the charged ions on the comb. The direction in which the stream is altered is dependant on the charge of the ions.well, Jonas brothers are great
What raw material was close in the ground that helped to make stream for great Britain?
Coal
What device opens and closes an electric circuit?
A switch is a device that is used to open and close an electrical circuit that is is connected into.
