Question

Какое из двух измерений точнее: 1) 895 м( ± 0,5 м) 2) 24,08 м( ± 0,01 м) Заранее спасибо.

Answer 1

Второе - точнее, т.к. в нем погрешность меньше

Answer 2

Comparing Measurement Precision

When comparing the precision of two measurements, it's important to consider the range of uncertainty associated with each measurement. In this case, we have:

1) 895 m (± 0.5 m) 2) 24.08 m (± 0.01 m)

The precision of a measurement is determined by the magnitude of its uncertainty. The smaller the uncertainty, the more precise the measurement.

The first measurement has an uncertainty of ±0.5 m, while the second measurement has an uncertainty of ±0.01 m. Therefore, the second measurement (24.08 m ± 0.01 m) is more precise than the first measurement (895 m ± 0.5 m).

This conclusion is based on the fact that the uncertainty associated with the second measurement is significantly smaller than that of the first measurement.

Conclusion

In summary, when comparing the precision of the two measurements provided, the second measurement of 24.08 m with an uncertainty of ±0.01 m is significantly more precise than the first measurement of 895 m with an uncertainty of ±0.5 m.
