Question

What is the largest distance(in a straight line) that can be measured with a meter scale of length 1m and smallest division of 1 mm?
A. \[1{\text{mm}}\]
B. \[1{\text{m}}\]
C. \[100{\text{m}}\]
D. No upper limit exists for measurement of length with a meter scale.

Answer 1

Hint:Meter scale is a device which is used to measure the length of any object. Meter scale measures the length in SI unit that is meter.A meter is defined as the distance of the path which is travelled by light in vacuum in \[\dfrac{1}{{299792458}}\]seconds.

Complete step by step answer:
The system of measurement which is used in the metric system is known as the Meter scale. This scale can be used many times to measure any length. From the meter scale we can measure any dimension, there is no upper limit to measure the length with a meter scale while measuring tapes are the stretchable measuring device which is used to measure the distances up to $100{\text{m}}$.distances. Another measuring tool is ruler which is used to measure small objects.

Therefore, No upper limit exists for measurement of length with a meter scale

Hence, the correct option for this problem is, D.

Note: For more understanding about the different units of length, we need to consider a few objects as an example from our daily routine.
1. Length of guitar, cloth pieces are measured in meters.
2. The thickness of the debit card, ID card is measured in millimeters.
