What are the basic metric units for length, mass, and time?
- a. Foot, pound, hour
- b. Newton, litre, second
- c. Metre, kilogram, second
- d. Mile, ton, day
Find the correct option.
Answer to Problem 1RQ
The correct option is, “c. Meter, kilogram, second”.
Explanation of Solution
The measurement of something (object) from one end to the other is called as the length of the object and is measured in meter. The basic metric unit for length is meter.
The measurement of quantity of matter present in an object with no specific shape is called mass of the object. Mass is quantified in terms of grams. The basic metric unit for mass is kilogram (100 g).
The duration elapsed between two events is called time. It is written in terms of seconds. The basic metric unit for time is second.
So, the correct option is ‘c’, as it reflects the same basic metric units
Option ‘a’ is wrong as it reflects Foot, pound, hour and these are not the basic metric units of length, mass and time.
Option ‘b’ is wrong as it reflects Newton, litre, second and these are not the basic metric units of length, mass and time.
Option ‘d’ is wrong as it reflects Mile, ton, day and these are not the basic metric units of length, mass and time.
Conclusion:
Thus, the correct option is, “c. Meter, kilogram, second”.
