How many significant figures does 546.000 have?
It has 3 because the 0's after the decimal point don't count as significant figures.
How many significant figures are in 4.005?
4 (the internal 0's count)
Definition of significant figures in physics?
significant figures are how many figures greater then zero starting at a point. for example; 784944 to 3 significant figures is 785000, where you stop at the third number, round it up or down and replace the rest with 0's.
How many significant figures can be recorded in the measurement of time on the stopwatch?
Depending on the type of the stopwatch, divisions of: 1/10 s, 1/100 s, 1/1000 s
How do you evaluate significant figure?
A significant figure is a bit like a decimal place, in that just how a maths question may ask for the answer 'to 2 decimal places' it may also be answered to '2 significant figures'. For example, say you have the answer: 3.1415926 To 1 decimal place it would be: 3.1 (because you round the 4 after the 1 down, because it is less than 5), because there is 1 digit after the decimal place (.) To (a certain amount) of significant figures, however, means the total amount of digits/numbers in the answer, for example: To 3 significant figures, the answer would be: 3.14 because there are now just 3 digits in the answer. However, a '0' does not count as a significant figure if it is before/after a set of regular (1-9) numbers (but it does count if it is in-between). For example: 0.00000454 This is still to 3 significant figures, because the '0's are before the other numbers, and so do not 'count'. The same can be said for: 45400000000 This is still to 3 significant figures, because the '0's are after the other numbers, so they do not count. However: 400045 This is NOT to 3 significant figures, because the '0's are IN BETWEEN the other numbers, and so they DO count as significant figures. Hope I helped :)
