Question

Consider the following processes:
1. Wind rotates the blades of the windmill
2. Electrical energy produced
3. Turbine rotates
4. Blowing of wind
Which of the following predicts the correct order of events?

• A. 1-2-3-4
• B. 4-3-2-1
• C. 4-1-3-2
• D. 3-2-1-4

Answer 1

The correct option is C

4-1-3-2

The blowing wind hits the blade of the windmill and rotates them. The blade in turn rotates the turbine which produces electricity. Thus the correct sequence of operations is 4-1-3-2.
