Which sound would be louder?
a wave with a low amplitude
a wave with a high amplitude
Which sound wave would have the most energy?
someone talking
a basketball bouncing
a lawnmower cutting grass
What does wavelength determine?
how loud a sound is
how soft a sound is
how high or low-pitched a sound is.
What is amplitude?
the distance from the middle of the point of the wave to the wavelength
the distance from one crest to the next crest

How do wind turbines work?
they use water to produce electricity
they transform electrical energy into motion
they use heat to produce electricity
they transform energy of motion into electrical energy
What part of the wind turbine produces the energy?
the generator
the blades
the electrical wires
One advantage of using wind turbines to produce electricity is that wind is what type of resource?
Renewable - we will never run out of these resources
Nonrenewable - will eventually run out of these resources
