Question

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. Describe the period for one graph. Explain your reasoning. Use the appropriate units. Which of these graphs appears to be the closest to a simple harmonic function? Explain your reasoning.

Answer 1

what????

Answer 2

post pics of the graphs

Answer 3

oh okay wait...sorry http://assets.openstudy.com/updates/attachments/4fd21eafe4b057e7d2212256-rini94-1339170503847-sleep.png

Answer 4

I am thinking that for the first function the period is from 6 am to 12 am...is that correct? if so how would i use appropriate units

Answer 5

the period of each graph seems to be 24 hours

Answer 6

was i right

Answer 7

how do i express that in appropriate units?

Answer 8

im not sure what you mean, the period is just 24 hours.

cant really write a function for it because it doesnt really give any numbers for the y axis

Answer 9

for b, would function a be the simple harmonic motion

Answer 10

yes the newborn appears to be the closest to simple harmonic motion

Answer 11

okay...i didnt really quite understand what the ques meant when it said "appropriate units" as well? maybe the units are hours

Answer 12

ya i guess

Answer 13

thanks, i just wanted to double check my answers :)

Answer 14

alright good luck in the ivy league, bum.

Answer 15

haha, Hopefully I get accepted into an ivy league by the time im done with high school. I think being a bum is quite sophisticated and UBER

Answer 16
