Final Answer:
The mass of an object may be measured in kg,So, the correct ption is b.
Step-by-step explanation:
Mass is a fundamental property of matter and is typically measured in kilograms (kg). The unit "kg" stands for kilogram, which is the base unit of mass in the International System of Units (SI). One kilogram is defined as the mass of a specific platinum-iridium alloy cylinder kept at the International Bureau of Weights and Measures. This definition provides a stable and reproducible reference for the measurement of mass.
The choice of kilograms as the unit for mass is based on the practicality and universality of the metric system. The metric system simplifies scientific calculations and promotes consistency in measurements across different scientific disciplines. It is important to note that mass is distinct from weight; while mass is an intrinsic property of matter, weight depends on the gravitational force acting on an object. The Newton (N) is the unit for measuring force, and weight is often expressed in Newtons. However, when measuring mass directly, the standard unit is the kilogram.
In summary, the correct unit for measuring the mass of an object is the kilogram (kg). This choice aligns with the established conventions of the metric system and provides a standardized and widely accepted method for expressing mass in scientific contexts,Thus, the correct option is b.
