Answer: As the "wind" pushes the blades and makes them to spin, kinda like an inverse process of how a fan works (where in the fan you impunt energy to make the blades move and generate wind, and in this case the wind makes the blades move to generate electricity), and this movement of the blades creates work that is transformed into electric energy.
Without the wind, you can not generate work in the blades, and then electric energy can not be generated, so you need this source to "push" and impulse torque in the blades.
D transferring electrons because that causes electricity
Only Condition for Resonance is-
It occurs when the first object is vibrating at the natural frequency of the second object. It always result into a big vibration/loud sound.
Resonance is process by which a vibrating system or an external force drives another system to oscillate with greater frequencies at specific frequencies called resonant frequencies. At resonance frequencies, small periodic driving forces have capacity to produce large amplitude oscillation.
∴ In given scenarios, the case which accurately describes a condition in which resonance can occur is-
C. A pipe's length is equal to 1⁄2 of the wavelength of the sound waves produced by a tuning fork vibrating over one end of the pipe that's open to the air at both ends.
