The absolute uncertainty for the total width of the two pieces of wood is 0.13 cm

What is Uncertainty ?

Uncertainty is inevitable error in a measurement. Some example are;

  • Systematic error
  • Random error
  • Absolute error
  • Percentage error
  • ETC

Given that two pieces of wood are measured and their widths are found to be 8.0 +/- 0.07 cm and 7.0 +/- 0.06 cm. What is the absolute uncertainty for the total width of the two pieces of wood if they are placed side by side?

The total Length = 8 + 7 = 15 cm

Uncertainty = 0.07 + 0.06 = 0.13 cm

In any question that involves plus or minus, their uncertainty will always be added.

The total width = 15 +/- 0.13 cm

Therefore, the absolute uncertainty for the total width of the two pieces of wood is 0.13 cm
