Answer:
Option B - 2
Step-by-step explanation:
We have given, the length of a spring when it’s at rest is measured to be 0.56 centimeter.
We have to find, how many significant figures are there in this measurement?
Solution :
The rules to get the significant figure are
- Non-zero digits are always significant.
- Any zeros between two significant digits are significant.
- A final zero or trailing zeros in the decimal portion ONLY are significant.
The given measurement is 0.56 cm.
It has two trailing zeros in the decimal i.e. 5 and 6.
There are only two significant figures.
Therefore, Option B is correct.

Step-by-step explanation:
In measurements, accuracy is a term that is used to describe the closeness of a measured value to the actual or true value. While precision describes how close different measured values are to each other.
Thus when a measured value is accurate, it implies that the value is very close or almost equal to the true value. The correct answer to the question is is option D.
