Question

A metre scale is graduated at every millimetre . How many significant digits will be there in a length measurement with this scale ?

Answer 1

Thanks for asking the question!

ANSWER::

The metre scale is graduated at every millimeter i.e. 1 m = 100 mm 

As we know the minimum no. of significant digit maybe 1 ( example for measurements like 2 mm , 9 mm etc. ) and also , maximum no. of significant digits may be 4 ( example 2000 mm).

So , the number of significant digits maybe 1 , 2 , 3 or 4 .

Hope it helps!

Answer 2

The significant digits will be there in a length measurement with this scale is 1, 2, 3 or 4.

Explanation:

• The metre (m) scale is graduated at each metric linear unit ( millimeter ) that's one meter = a hundred metric linear unit .
• As we all know the minimum variety of serious digit is also one (example for measurements like 23 millimeter , eight metric linear unit etc. ).
• Also , maximum no. of serious digits is also four ( example one thousand mm).
• So , the no. of serious digits is also (anything) one , 2 , 3 or 4.

Therefore, the significant digits may be 1, 2, 3 or 4.
