Answer :
Final answer:
The metric dial indicator graduation scale numbers identify the position of the dial needle, which is crucial for precision measurements in scientific and engineering contexts. The correct answer is 1).
Explanation:
Position: This applies to tools used for precision measurements such as micropipettes and graduated cylinders where accurate readings are vital. The graduation scale helps to pinpoint an exact location on the scale that corresponds to the measurement being taken.
For example, when using a graduated cylinder, each number on the scale might represent one milliliter, and the numbers in between the main graduations allow for an estimate of the volume to the nearest 0.1 milliliter. Similarly, when adjusting the volume on a micropipette, turning the knob sets the volume to three digits, and the vernier marks can help in extrapolating the volume for more precise measurements.
These tools typically offer accuracy to several significant figures, emphasizing the importance of reading them correctly to ensure precise measurements in scientific and engineering applications.
