what does "100 c in a r" mean????

I don't really get what you mean..

10^100 - 10^-100... That's pretty close.. hehe

Where it gets confusing is from 33 degrees really, and you then have to rely on the geographical position of the person making the statement. Obviously if you are talking to someone in the same place as you the question of F or C doesn't arise.\nIt shows that we should be more careful what we say, especially to a wider audience, who as on here could be situated anywhere in the world.\nIf I said 33 degrees, knowing I live in the tropics you would assume centigrade (91F).\n\nRight who fancies a pint of beer at fifty degrees, and who fancies a litre of ale at fifty degrees.

In this area it occasionally reaches 100 F.

most likely "centi-."\n\nit means one-hundredth.\n\n\nhope that helps.

Suspect this is what you mean...\n\nSuppose you have 0.500 g of a substance you believe is pure...\nyou analyse it and determine that it contains 0.300 g of the substance you are looking for..\nso your sample is (0.300/0.500) x 100% pure  = 60%

1.25 = 125/100 = 5/4\n\n.

what it means is this 4 plus negative .01 and with the other it's 5 plus negative .04 its simple. if you know what it means and if you took notes look at them. it may help a little

Celsius or Centigrade

This is an old math riddle.  Mathemeticians and physisists like to refer to absolute zero (Kelvin scale, with no negative numbers), instead of Fahrenheit or Celsius (which are relative to the freezing and boiling points of water at sea-level).  \n\nTechnically, in a relative scale it makes no sense to speak of doubling or halving the temperature.  (If it is 0 degrees (F or C), then doubling or halving would still be 0, which makes no sense.)  \n\nA less scientistic but more human approach is to postulate a base temperature that most people find comfortable.  Let's say it's 70F (21C, 294 Kelvin, 529 Rankine, 17 Reamur).  If today is "cold", it means less than 70F.  E.g., maybe today was 50F.  So it was 20 degrees (F) colder than is comfortable (70 - 50 = 20).  If tomorrow will be "twice as cold," it will be 70 - [2 x (70 - 50)] = 70 - (2 x 20) =  30F.  Quite cold!

Actually the above answer (and source) is incorrect.  In most situation there is a difference.  "C"alorie, in the capital sense is meant to denote a kilocalorie, or 1000 "c"alories (in the lowercase sense).  Every Calorie on the back of the food boxes are indeed 1000 calories.\n\nThe problem is that these two terms are often misused, and misrepresented.  A calorie in laymans terms is actually a kilocalorie, but rather than saying all of that, and making it a markedly more confusing term, it was simplified to Calorie.\n\n\n\nTiger Striped Dog MD

I think you're talking RF not audio and the given C value sounds just fine. We pretty much agree except for the decimal point, unless you are using a comma for the d.p.\nI get f = v/lambda = 299792458/5.7 = 5.259517E+07 Hz, \nw = 2*pi*f = 3.304652E+08 rad/s, and \nL = 1/(w^2*C) = 1/(1.092072E+17*1.9E-12) = 4.819422E-06 H or 4.819 uH.

Are you looking at computer code?  B indicates binary base and D indicates decimal.\nB100 = 1*2^2 + 0*2^1 + 0*2^0.\nD1000 is one-thousand.

okay...100 g*(mol/12.01g)=8.33 mol C\n\ntake the aforementioned 1mol *(-113kj/2mol)=-56.5 kJ released for 1 mol\n\nthen multiply that -56.5 by 8.33= -470.65 kJ released\nnote it is exothermic and thus negative

It means you get 100 for $29.99 or whatever price.  What are you ordering, dear?  I always capitalize.  It shows you are educated.

Centigrade is another term for celcius. They are terms for the measurement of temperature. The actual word Centigrade comes from the fact that the graduations on the celcius or centigrade scale are based around 100 degrees between the freezing and boiling point of water at STP. Hence centi(or one hundredth) and grade( gradient).

It has to do with the type of liquid you are using. For water it is 1000 Milligrams=1 C.C.\n\nC.C. is a way to measure volume. For example: the C.C.'s of 1 mg of cotton is more than that of 1 mg of gold.
