Question

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

✓

Answer

The metre scale is graduated at every millimeter.
1m = 100mm
The minimum no. of significant digit may be 1 (e.g. for measurements like 5mm, 7mm etc) and the maximum no. of significant digits may be 4 (e.g.1000mm)
So, the no. of significant digits may be 1, 2, 3 or 4.

⁵⁷Co decays to ⁵⁷Fe by $\beta^+-\text{ emission.}$- emission. The resulting ⁵⁷Fe is in its excited state and comes to the ground state by emitting $\gamma-\text{rays}.$ The half-life of $\beta^+-\text{decay}$ is 270 days and that of the $\gamma-\text{emissions}$ is 10^-8 s.
