What is the principal difference between amplitude and frequency in the context of sound waves?

A) Amplitude is the tone or timbre of a sound, whereas frequency is the pitch. B) Amplitude is detected in the cochlea, whereas frequency is detected in the auditory cortex. C) Amplitude is the height of the sound wave, whereas frequency is a measure of how frequently the sound waves pass a given point. D) Both measure qualities of sound, but the frequency is a more accurate measure since it measures the shapes of the waves rather than the strength of the waves. E) Frequency is a measure for the light waves, whereas amplitude is a measure for sound waves.

According to Piaget, the three main processes that guide our interactions with the environment are

A) scaffolding, mediation, and internalization. B) biological maturation, mediation, and collaborative learning. C) organization, adaptation, and reflective abstraction. D) adaptation, scaffolding, and operational thought.
