Difficulty: Easy
Choose an option
Answer
Correct Answer: Watt
Explanation
Introduction / Context:Metre is the SI unit for length. We must select the SI unit for power.
Given Data / Assumptions:
- Use standard SI base/derived units.
Concept / Approach:Power is measured in watt (W). Joule measures energy, kilogram measures mass, degree is temperature/angle, calories measure energy in another system.
Step-by-Step Solution:
Map quantity → SI unit: power → watt.Verification / Alternative check:Physics convention confirms watt for power.
Why Other Options Are Wrong:They are units of different quantities.
Common Pitfalls:Confusing energy (joule/calorie) with power (rate of energy).
Final Answer:Watt
