Question

PLEASE HELP ME !! STUCK ON THIS!

Which choice describes the purpose of the blades in a wind turbine?

A) The blades convert wind energy into rotational energy.

B) The blades include a gearbox and a generator.

C) The blades create charges inside an electromagnet.

D) The blades provide structural support to the turbine.

Answer 1

A) The blades convert wind energy into rotational energy.

Step-by-step explanation:

Wind turbines use blades to collect the wind's kinetic energy. Wind flows over the blades creating lift (similar to the effect on airplane wings), which causes the blades to turn. The blades are connected to a drive shaft that turns an electric generator, which produces (generates) electricity.

Answer 2

A is the basis for all of the other assumptions.

Everything else supports A.
