Introduction :
A standard unit of measurement is a quantifiable language that allows everyone to understand the association of the object with a uniform measurement and therefore, reduces or minimises the rate of confusion or mistakes.
The SI base units are the standard units of measurement defined by International System of Units for seven basic physical.
Answer to Problem 11A
Correct answer :
The correct answer is option (B) Kilogram.
Explanation of Solution
Explanation/justification for the correct answer :
Option (B) Kilogram. The kilogram (kg) is the SI base unit for mass. Mass is a measureable quantity as it is the quantity of matter contained in the body and it is an important physical characteristic. The physical characteristic of dolphins is mass and measurable as kilogram. So, the correct answer is option (B).
Explanation for incorrect answer :
Option (A) Second. Second is the SI base unit for measurement of time. So, this is an incorrect answer.
Option (C) Inches. Inches is a measurement unit of length in the United States customary system. So, this is an incorrect answer.
Option (D) Gallon. Gallon is a measurement unit of capacity in English speaking countries. It is equal to four quarts. The U.S. standard gallon is equal to 231 cubic inches and British imperial gallon is equal to 277.42 cubic inches. So, this is an incorrect answer.
