The time taken by a vehicle to go from one station to the other is 100 s. It is recorded with a stop watch having the least count 1s. How many significant figures are there in the value of the time 100 s? How?
Dear Student
Any number used in a calculation or actual measurement should contain only figures that are considered reliable; otherwise, time and effort are wasted. Figures that are considered reliable are called significant figures
100 s has 3 significant figures as it is recorded by stop watch having least count 1 s, so reliable figure in 100 s is 3.
If you talk only about number 100 then significant figure in it 1. As it is simple number and zero on RHS on non decimal number are not considered as significant number but in actual measurement this rule has exception.
