Basic Quantities 46Dea6
1. The problem asks to identify which set of quantities are considered basic quantities in physics.
2. Basic quantities, also known as fundamental quantities, are those that cannot be derived from other quantities. They form the foundation of measurement systems.
3. The seven basic quantities in the International System of Units (SI) are:
- Length
- Mass
- Time
- Electric current
- Temperature
- Amount of substance
- Luminous intensity
4. Now, let's analyze each option:
- A. Length (basic), electric field strength (derived), temperature (basic)
- B. Mass (basic), amount of substance (basic), electric current (basic)
- C. Weight (derived), time (basic), temperature (basic)
- D. Length (basic), energy (derived), time (basic)
- E. Mass (basic), area (derived), amount of substance (basic)
5. Only option B contains quantities all of which are basic quantities.
Final answer: Option B: Mass, amount of substance, electric current
