Question

1. human sleep/awake cycles at three different developmental stages are illustrated in the graphs below. the parts of the graph that lie above the horizontal axis represent times when the person is awake, while those parts below the axis represent times when the person is asleep.

a. describe the period for one graph. explain your reasoning. use the appropriate units.

b. which of these graphs appears to be the closest to a simple harmonic function? explain your reasoning.

Explanation:

Answer:

a. For the Adult graph, the period is 24 hours, as the cycle repeats over one full day from 6 AM to the next 6 AM.
b. The Newborn graph appears closest to a simple harmonic function, as it has regular, symmetric oscillations above and below the axis with consistent wavelength.
