(a) What is the measurement uncertainty of this Vernier Caliper?

$LaTeX: \delta L=$ ___ cm

(b) What is the main scale's measurement?

LaTeX: L_1= ___ cm

(c) What is the Vernier scale's measurement? You will need to zoom in on the picture.

LaTeX: L_2= ___ cm

(d) What is this object's total length?

LaTeX: L=L_1+L_2= ___ cm

Please explain, I know it's easy.

Answer 1

Answer #1

a) Measurement Uncertainty = ± 0.01 cm

b) L₁ = 0.7 cm

We will look the where is the 0 of vernier scale is to the main scale

c) L₂ = 0.048 cm

We look where the scale of vernier in line with main scale and multiple vernier scale reading with least count

16 × 0.002 cm = 0.048 cm

d) L = 0.748 cm

The "best" result is always associated with the measurement with the smallest uncertainty. Measurement B has half the standard uncertainty of measurement A. Therefor e our 68 % coverage probability is associated with a smaller interval (83.44 g o 83.56 g) for measurement B than measurement A (83.38 g to 83.62 g). In other words we have better knowledge about the value of the measurand from measurement B, since we have the same coveroge probability associated with a norrower interval....
