Which of the following is the correct order?
Correct answer: C. 1kwh>1J>1erg
- A. 1kwh>1erg>1J
- B. 1J>1erg>1kwh
- C. 1kwh>1J>1erg
- D. 1kwh=1J=1erg
Explanation
The explanation of this question is: 1KWh=3.6 ×106joules 1 joule=107 erg hence 1KWh>1joule>1erg

About Work and Energy
Work transfers energy when a force causes displacement, while kinetic energy, gravitational potential energy and power describe motion, position and the rate of energy transfer. The work-energy theorem links net work with change in kinetic energy, and efficiency accounts for energy losses rather than treating them as energy destruction.
