by significant figure ​

Answer 1

Answer:

Significant figures are the number of digits in a value, often a measurement, that contribute to the degree of accuracy of the value. We start counting significant figures at the first non-zero digit. Calculate the number of significant figures for an assortment of numbers.

Answer 2

Explanation:

Every measurement involves errors. Thus, the result of measurement should be reported in a way that indicates the precision of measurement. Normally, the reported result of measurement is a number that includes all digits in the number that are known reliably plus the first digit that is uncertain. The reliable digits plus the first digit are known as significant digits or significant figures.

Eg. If we say that

the period of oscillation of a simplependulum=1.62 s the digits 1 and 6 are reliable and certain, while the digit 2 is uncertain.

Thus, the measured value has three significant figures.
