The question is:  What should I set on the sub-scale of my altimeter so that the instrument would indicate my elevation if I were on the ground at your station?\n\nANSWER:  QNH

it is the average amount that each sample (or reading number) deviates from the mean (average). It is a measure of how widely the data is scattered away from the mean.\n\nThis is highly simplified, you might want to look on wikipedia for a better explaination. (it involves square roots and other nasty maths)

1) A scale is the unit to measure the mass and volume of a specific object.\n2) Weight measurer? (I am not very sure of this)\n3) It depends. If it is digital, you can simply read the number reading but if it is manual, you have to look at the "small lines" that indicate the mass and volume of an object shown in kilograms or something like that.\n\nI am not sure that all of this are correct but I hope this would give you clues to your answers. Good luck!

I'm assuming you are using an op amp.  The offset voltage is a value given to help assist you in modelling a device.  The offset voltage is a parameter that describes a voltage at the input of the op amp between the noninverting and inverting inputs.  The voltage arises because of the asymmetry in the fabrication of the device.  You'll have to look at the data sheet closely to see how it is measured, or taken care of in your specific device.

its the point which you are rotating the object around

Its refering to sunlight. Only sunlight goes low or dim (We were afraid that the light was too low)

Depends how the  maschine is calibrated

Your computer CRT screen is like a Tube Television. The image being show is broken down into rows and columns. Almost like an excel spread sheet only zoomed out so that each cell in excel, is a single dot (pixel) on your screen. 1024 x 768 means that there are 1024 pixels (columns) by 768 pixels (rows).\n\nThe quality of a monitor is relative to the number of clear pixels that can be shown accurately without being distorted. Which is why there have always been cheap and expensive 17" monitors... or 19" or 21", etc... Ya, they are 17" but the size of the pixels and the maximum number of pixels it can display clearly dictates the prices...\n\nYour CRT tube (Cathode Ray Tube) monitor, has a phosphorus coating on the inside of it's glass front. When the "Ray" hits the phosphorus on the tube, it glows for a period of time then stops glowing. These little glowing areas of phosphorus are your pixels. If you can picture the Ray, almost like a laser beam.... "scanning" a single row of pixels at a time, moving down one row and scanning that row, then moving down a row and scanning that row, etc... for however many rows you have (say 768), that is a single pass. 60Hz, refers to the number of times per second that a pass happens. (on a side note, this is what causes "monitor burn in or ghosting"... if the same image is displayed long enough all the time, the phosphorus actually wears out leaving a ghost of the image when the monitor is turned off). Kind of like when you look at a light then close your eyes... you can still see the outline in the dark.\n\nThe human eye has Persistance of Vision (POV) which is a very interesting term. But in a nut shell, if you take a sparkeler from a birthday cake and swing it around fast enough, you can make shapes or letters... Your eye, keeps the position of the light for a few milliseconds  but instead of taking say 60 individual snapshots of the dot of light, it blurs/merges it all together to form a single stream of light. The light "persists".\n\nThat stream (rows of streams really), is what makes a picture on the screen. The faster refresh rate indicates that that picture (stream of pixels) is redrawn or updated (in the case of a moving/changing image), 60 times a second (60 Hertz) or 85 times a second (80 Hertz)... The quality of your monitor, will limit the speed it can refresh at with certain resolutions. The higher the resolution (say 1600x1200), the less ability the monitor usually has for it's refresh rate (could drop down to 60Hertz).\n\nGenerally speaking, at 60 Hertz, you can see a slight flicker... You might get a headache over time... 72 Hertz, your eyes stops seeing flicker... 85 or higher, you will not notice the differences, but your monitor is forced to work harder... I would suggest 85/80 Hertz and not to worry if you can only get 72 Hertz.\n\nBack in the days, you could buy "Interlaced" or "Non-Interlaced" monitors. Interlaced were cheaper monitors. And you should note, that some monitors will actually kick into Interlaced mode at higher resolutions, so that they can display the image, but at a crappy refresh rate.\n\nIn fact what is happening... the "ray" is skipping a line every time it does a pass, then on it's next pass, draws in the missing lines, then repeats. It interlaces the lines. The "Ray" is pretty much doing the same amount of work it would do without interlaced, except it's taking two passed to show the completed picture. So, you are getting 1/2 the performance... This usually frees up circutry to allow it to display higher resolutions images.  Your eyes, notice a flicker, but you don't notice much else. The image is displayed... cheaper parts are needed to show the higher resolution images at a crappy refresh rate.\n\nInterestingly enough, you do not notice much of a "flicker" when you have a moving image on screen... In fact, your televis

It means a number between 5 and 200.  You might have to round to the nearest number if it doesn't take decimals.

This is from my software testing days but I believe checking syntatic accuracy/correctness is basically where you analyze the syntax of your code to see if there are problem spots like for instance checking a loop to see if there is a chance it might become an infinite loop and end up just bogging the system down.

It indicates what is already known which can then show you what else is not yet known.  It can also tell you what questions have been asked, what questions there is some kind of answer for, and what questions need to be asked.

Not accurate or worth it.\n\nThis is a simple/relatively cheap test to have done at the doctor's office.  It's WAY more worth it than saving just a few bucks for inaccurate results from a home test.

i use to work in several water treament facilities. a flow meter is calibrated with the rising and lowering of the water level. the best flow meter utilizes a float inside a pipe that is slightly larger than the float.go to www.grainger.com. they have pictures of a few flow meters

I agree; c) is the right choice.  The other units are used to measure:\n\na)  power ratio\nb)  pressure\nd)  pressure (again)

I think one has to recalibrate your barometer for every different location (including altitude), according to what I read on the internet and my intuition. \n\nI am working on a more quantitative analysis which I will try to complete to post here later.

To my knowledge one is unable to calibrate a manual sphygomanometer at home.  Even in the hospital, the gauge, rubber bladder,sleeve, valve and tubing were replaced.  They sometimes bought replacement parts but more often cannibalized parts from another...Call the manufacturer and see what they say...
