The minimum velocity required for obtaining useful energy with the windmill is about
15 km/h
35 km/h
45 km/h
60 km/h
Explanation
Hence, option (a) is the correct answer.
what causes the wind to blow? what is the minimum wind velocity required to obtain useful energy with a wind mill? Electricity generated by a wind mill is another form of solar energy. Explain.
Oxygen is required for obtaining energy from food.
