Question

Which unit will you use to find the length of your notebook and why?

Answer 1

Hint Think of this yourself, what is going to be the meaning of the length of an object if we can’t measure it. We will then inform its length subjectively as ‘long’, ‘short’, etc. That makes no sense anymore now.

Complete Step-by-step solution
Measurement is the process by which we measure a physical quantity using a definite instrument for that quantity. The unit is a quantity of anything that can be measurable in different ways, the rice is measured in Kgs because it is uncountable, so it is measured by weighing. Similarly, the distance is measured in kilometers, meters, centimeters, millimeters, miles, etc.
The unit of distance in the metric system is measured in meters.
For example, the distance between the Yash and Navneet house is 1km or 1000m or 100000cm and 1000000mm .
The liters are used as the unit of liquid forms like water, oil, etc.
The gram is used as the unit for the quantity of any products.
The second is used as the unit for the time, 1hour is equal to 60min and 1min is equal to the 60sec .
Therefore, the answer is ‘Centimetre’. Because a notebook has a length for which meter would be a huge unit to measure and a millimeter would be a lesser one.

Note The units will be considered differently in other systems, for example, the distance is measured in meters only in the metric system but when it comes to the other standards like the U.S, and then the distance is measured in miles.
