Question

What is the smallest scale increment of the ruler shown in fig. 4, above?

What is the length of the line above the "Klump" scale in Figure 4, above? How much uncertainty is there in this measurement?

What is the smallest scale increment of the ruler shown in fig. 5, above?

What is the length of the line above the "Glip" scale in Figure 5, above? How much uncertainty is there in this measurement?

Answer 1

8. In figure 4, the smallest scale increment is 10 units length

9. The length of the line above the "Klump" scale in Figure 4 is 75 ± 5 units length. The uncertainty is ± 5 units length. This means that the measure is between 70 and 80.

10. In figure 5, the smallest scale increment is 0.1 units length

11. The length of the line above the "Glip" scale in Figure 5 is 1.45 ± 0.05 units length. The uncertainty is ± 0.05 units length. This means that the measure is between 1.4 and 1.5

Answer 2

74 ± 1 klumps; 1.44 ± 0.01 glips

Step-by-step explanation:

8. Smallest scale

There are no divisions between 0 and 10, so the smallest scale division is 10 klumps.

9. Length of line

You should estimate to the nearest tenth of the smallest scale division.

The line appears to be slightly less than half-way between 70 and 80.

I estimate the length of the line to be 74 klumps, with an uncertainty

of ±1 klump.

10. Smallest scale division

There are 10 divisions between 0 and 1, so the smallest scale division

is 0.1 glip.

11. Length of line

The line appears to be slightly less than half-way between 1.4 and 1.5.

I estimate the length of the line to be 1.44 glips, with an uncertainty

of ±0.1 glip.
