How many significant figures are in 100 cm?
Integers ending in zero(s) are ambiguous. There is no way of telling whether the measurement was taken to the nearest metre and expressed in cm (1 significant digit) or measured to the nearest centimetre (3 sig fig).
Why is accurate body measurement important how are body measurement taken?
no
Accuracy refers to the level of detail to which a measurement is taken?
False
Why do you think accurate measurement of time became possible much after accurate measurement of length and mass?
Accurate measurements of time become possible after accurate measurement of length and mass because time taken by a heavy body to move a certain distance is more,and time taken by a light body to move a certain distance is less.
What is meant by the phrase a consistent method of measurement?
measurements are taken in a way that is the same every time. - apex
How many significant figures are in the number 1039.520?
Seven (7) significant figures. All digits left of the decimal to the right of any leading zeros. All digits to the right. The zero is counted because it is significant that the measurement was taken to that level of precision. The full measurement may have been 1039.5201, .5202, etc. For whatever reason, the measurement was taken to 3 digits to the right of the decimal.
How many significant figures are in 9.3220895?
8 By definition, all the figures are significant (no rounding off appears to have taken place). There are eight significant figures.

What are significant figures-?
When a number is written in scientific notation, the digits that do not appear are not significant. The rest are significant figures. For example, when you convert 0.0003102 to scientific notation, it is 3.102 X 10-4. Therefore the zeros before the 3 are not significant.The 3 significant figures implies to all digits around it, regardless of before and after the decimal point. 8.00 has 3 sig.figs. This is because of the 2 zeroes after the decimal point. When you have 30 zeroes after the decimal point, such as 3.000000000000000000000000000000, you have 31 significant figures. 1.23 has 3 sig.figs. This applies to all questions, if needed.The amount of figures given in an answer where you begin with approximates of numbers. The answers should not be more precise than the original measurements. This would lead to a misleading answer, and thus significant figures were created to show an accurate approximation of your answer.The idea of significant figures (sig figs or sf), also called significant digits (sig digs) is a method of expressing error in measurement.The most significant digit is the "first" digit of a number (the left-most non-zero digit). Similarly, the least significant digit is the "last" digit of a number (sometimes, but not always, the right-most digit). A number is called more significant because it carries more weight. In the decimal number system (base 10), the weight of each digit to the left increases by a multiple of 10, and conversely the weight of each digit to the right decreases by a multiple of 10. A similar thing happens in the binary (base 2) number system - see most significant bit.Sometimes the term "significant figures" is used to describe some rules-of-thumb, known as significance arithmetic, which attempt to indicate the propagation of errors in a scientific experiment or in statistics when perfect accuracy is not attainable or not required. Scientific notation is often used when expressing the significant figures in a number.The concept of significant figures originated from measuring a value and then estimating one degree below the limit of the reading; for example, if an object, measured with a ruler marked in millimeters, is known to be between six and seven millimeters and can be seen to be approximately 2/3 of the way between them, an acceptable measurement for it could be 6.6 mm or 6.7 mm, but not 6.666666... mm as a recurring decimal. This rule is based upon the principle of not implying more precision than can be justified when measurements are taken in this manner. Teachers of engineering courses have been known to deduct points when scoring papers if excessive significant figures are given in a final answer.Each of the digits of a number that are used to express it to the required degree of accuracy, starting from the first nonzero digit.Significant figures (also called significant digits) can also refer to a crude form of error representation based around significant figure rounding.Significant figures are digits that show the number of units in a measurement expressed in decimal notation.
How many minutes are in 2 000 hours in significant figures?
2000*60=120 000 as 2000 is taken to have only one significant figure, we have a result of 100 000
Why is accurate body measurement important how are body measurement taken?
no
What is a measurement taken with the aid of the senses is?
That type of measurement would be referred to as a qualitative measurement.
When do you use took or taken in a sentence?
TOOK is only used for the simple past tense of to take(e.g. "He took the ruler from the desk.")TAKEN is the participle form, used in these tenses :Present perfect ("He has taken the ruler.")Present passive tenses ("It is taken." "It is being taken." "It has been taken.")Past perfect ("He had taken the ruler before.")Past passive tenses ("It was taken." "It was being taken." "It had been taken.")Future perfect ("By tomorrow, he will have taken the ruler.")Future passive tenses ("It will be taken." "It will be taken." "It will have been taken.")(The participle form can be used as an adjective, e.g. "That seat is taken.")
Why are several observation taken for each measurement?
Several observations are taken for each measurement to eliminate or decrease the margin of error.
Why can't we write numbers with as many significant figures as we want?
Because some part of your equation has a figure that limits how many sig figs you can use. Remember the number of sig figs is symbolic of how precise the initial measurements were. For example the number 2.4 is not as precise as 2.45298. So your answer can only be as precise as the LEAST precise measurement you have taken or been given. So in my example above if 2.4 is the least precise measurement then you can only have an answer with two sig figs.
