All the food that you eat in one day has about the same energy as _ liter of petrol
Correct answer: B. 1/3
- A. 3
- B. 1/3
- C. 9
- D. 1/9
Explanation
The energy content of food is typically measured in calories. A calorie is a unit of energy. The energy content of petrol is also measured in calories.A typical adult consumes around 2000 calories per day. One liter of petrol contains approximately 6000 calories. Therefore, the energy content of food consumed in a day is about 1/3 of the energy content of one liter of petrol.

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.
