What are the significant figures in 314.721 meters four?
If you mean "How many significant figures are there in 314.721 meters then the answer is 6.
What does significant figures means?
it mean signs
How is precision related to the significant figures in a measured quantity?
The greater the number of significant figures, the greater the precision. Each significant figure increases the precision by a factor of ten. For example pi = 3.14 is accurate to 3 significant figures, while pi = 3.14159 with 6 significant figures is a more accurate representation.
What does nsf 2 mean?
Probably "number of significant figures = 2".
How many significant figures are in the measurement 811.40 grams?
There would be five. The only time you do not count figures as significant is if they are zeroes behind a decimal, but before any other figure. Ex/ 0.000501 only has three significant figures, while 1.000501 has seven.
What is 144.78 rounded to 2 decimal places?
Exactly what you typed. 144.78 rounded to 2 decimal places is 144.78. You may mean significant figures, in which case it would be 1.4*10^3 (2 significant figures).
How many significant digits are in the number 0.007080?
It has 4 significant figures.0.007080 has four significant digits.
How many significant figures are in 100?
If you are looking at this from a maths perspective, the 'significant figures' are the number of digits counting from the first non-zero digit, so the number of significant figures in 10.0 is three. You may be asked a question, and told to give the answer 'to three significant figures'. This would mean the answer would look something like '12.2' or '0.0254'. This is in contrast to decimal places, which refer to the number of digits after the decimal point. For example, the number 10.0 is quoted to one decimal place.
Using proper signification figures what is the answer to the problem 55.0 m s 3.027 s?
It isn't clear what the question is. If you are supposed to multiply or divide, and if by "signification figures" you mean significant digits, do the multiplication (or division), then round to three significant digits - since the least-precise of the numbers only has three significant digits.
Why you need to follow the significant figures?
The rules of "significant figures" tell you how many of the digits in your answer can be trusted and how many are trash. Without knowing those rules, you may get an answer with 15 digits in it, and think that you have the greatest answer there could be, and not realize that the last 12 digits are wrong and don't mean anything.
Examples of significant figures?
significant figures are digits of certainty. In other words they are exact numbers. Except zeros are placeholders (not exact) unless if they are in between non zeros. Also zeros at the end of numbers are significant figures if there is a decimal point.
What is signitifcant figures?
I believe you mean significant figures. Take an example. If you measure the length of a table as 1.52 m and its width as 1.46 m, each is measured to the nearest cm, and the values have just 3 significant figures. So the area of the table could be calculated as 1.52 x 1.46 = 2.2192 m2. But as the length could actually be between 1.515 and 1.525m, and similarly for the width, the area of the table could be between 1.515 x 1.455 = 2.2043 m2 and 1.525 x 1.465 = 2.2341 m2. So the answer should be given to 3 significant figures (2.22 m2) as the 4th and 5th figures are not significant. As a general rule, in multiplication and division the number of significant figures given in your answer should be no more than the smallest number of significant figures found in any of the numbers used to do the multiplication (or division). 4.5 x 4.653 x 3.234 = 67.715109 = 68 to 2 sig.figs.
