Answer 1

hey here is your ans

《《《《□□The term significant figures actually refers to particular digits in a number.□□□□》》》》
Only those figures or digits of a numerical quantity which are the result of actual measurement are said to be significant. For example, if you measure the thickness of a coin, you can write it as

1.6 mm or 0.16 cm or 0.0016 m.
How many significant figures are there in this measurement? Clearly only the digits 1 and 6 are the actual measured values. Therefore we have only 2 significant figures. Zeros used as placeholders are not significant. This would include all of the zeros in 0.0016 m

hope it hlps...
