Answer to Question #241584 in Physics for paul warren ilagan

Question

The standard mass of an unknown substance is 15.6g. Which of the following set has the least accurate value? Show solutions

Trial A B C

1 15.6 15.8 15.6

2 15.4 14.6 15.5

3 15.6 14.7 15.8

Answer 1

The least accurate value is the most different from the standard one:

$$\delta_1=15.8-15.6=0.2\text g,\\ \delta_2=15.6-14.6=1.0\text g,\\ \delta_3=15.6-14.7=0.9\text g.$$

Therefore, the second set has the least accurate value.
