The correct Answer is:
To solve the question regarding the set of quantities that can form a group of fundamental quantities in any system of measurement, we will analyze the provided combinations of quantities and determine if they include the fundamental quantities. ### Step-by-Step Solution: 1. **Identify Fundamental Quantities**: The fundamental quantities in physics are: - Mass (M) - Length (L) - Time (T) - Electric Current (I) - Temperature (Θ) - Amount of Substance (N) - Luminous Intensity (J) 2. **Analyze the First Combination**: The first combination consists of: - Velocity (V = L/T) - Acceleration (A = L/T²) - Force (F = M*L/T²) Here, we can see that: - Length (L) is present. - Time (T) is present. - Mass (M) is present. This combination includes all three fundamental quantities: Mass, Length, and Time. 3. **Analyze the Second Combination**: The second combination consists of: - Energy (E = M*L²/T²) - Velocity (V = L/T) - Time (T) Here, we can see that: - Length (L) is present. - Time (T) is present. - Mass (M) is also present in the energy formula. This combination also includes all three fundamental quantities: Mass, Length, and Time. 4. **Analyze the Third Combination**: The third combination consists of: - Force (F = M*L/T²) - Power (P = Work done / Time = M*L²/T³) - Time (T) Here, we can see that: - Length (L) is present. - Time (T) is present. - Mass (M) is present in both force and power formulas. This combination also includes all three fundamental quantities: Mass, Length, and Time. 5. **Conclusion**: Since all three combinations analyzed (velocity, acceleration, force; energy, velocity, time; force, power, time) contain the fundamental quantities of mass, length, and time, we can conclude that all the combinations are valid. 6. **Final Answer**: Therefore, the correct answer to the question is: **All the above**.
