Question

The diagram above shows a wind turbine. How does a wind turbine produce electricity? A) Energy from the Sun turns the rotor blades that turn the generator to produce electricity. B) Heat reflected from mirrors turn the rotor blades that turn the generator to produce electricity. C) Flowing Water turns the rotor blades that turn the generator to produce electricity. D) Moving air turns the rotor blades that turn the generator to produce electricity.

Answer 1

Wind turbines produce electricity from wind.
Sun energy is harnessed from solar panels, and does not power wind turbines.
Wind turbines don't work by heat at all, and some, if not all, wind turbines don't even have mirrors.
Water mills convert flowing water into energy.
So the answer is D) Moving air turns the rotor blades that turn the generator to produce electricity.

Answer 2

D = Moving air turns the rotor blades that turn the generator to produce electricity

Step-by-step explanation:

wind - mechanical energy - Electrical energy

A wind turbine is majorly found in areas with adequate wind. It consists of rotors, which are blades (similar to propellers) which by drag force increases the kinetic energy (which we know kinetic energy is a function of mechanical energy) of these blades by constant rotating speed caused by the air/wind pressure. this then spins an already installed shaft (in a turbine).

This turbine turns a generator which then converts this kinetic energy generated into electrical energy. this electrical energy is then taken to a transformer (to either step-up or step-down) before use.
