Four research teams measured the rotation period of a newly detected neutron star, and what each team wrote in its team notebook is shown in the table below. Suppose a later and more reliable measurement gives 0.710s for the period of the same star Decide which of the earlier measurements was the most accurate, and which was the most precise. Team what was written in the notebook most accurate measurement most precise measurement
A 0.70sec
B 0.71s
C 0.75 ± 0.002s
D B/w 1.05s and 1.115s

Explanation:

The correct measurement is .710 s which is equal to .71 s so second measurement that is 0.71 s is most accurate measurement .

B.  0.71s is the most accurate .

Precision depends upon measuring instrument . Measurement by highly precise instrument has greater precision .

The measurement of 0.75 ± 0.002s must have been taken from high precise instrument because it is capable of making measurement upto 3 decimal points .

Hence

C 0.75 ± 0.002s is most precise measurement .
