Question

Will Medal Which scenario(s) describes periodic behavior? Check all that apply.

Answer 1

Your body temperature

The movement of tides

The movement of a hurricane

Jumping on a trampoline

Answer 2

I'm thinking a, b, and c. Not quite sure though.

Answer 5

Hello! Periodic just means that it has some trend that's repeated over and over.

I think I saw somewhere that body temperature sort of does this since it drops when you sleep and rises when you're awake, but it also changes everyday. If you exercise today, and not tomorrow, you'll be seeing a very different trend. So I'm not sure if that counts!

Answer 6

It might, I don't know!

Answer 7

not c I meant d

Answer 8

The movement of the tides is probably pretty periodic - we even know the times for high tide and low tide because we know how the trend repeats. Not the same every time, but it does seem periodic.

And I agree with your change! I don't know all about hurricanes. But they seem like they form, move, die, and then they're done. There might be something that makes them periodic, but I don't know of any trends. I'm also not a meteorologist at all!

And the jumping on a trampoline can be VERY periodic. The child will jump the same way, go up, go down, repeat.. Trampoline will bend similarly every time, that sounds periodic.

Answer 9

Thank you! I'm going to go with b and d

Answer 10

Okay, I wish you luck. I hope I haven't steered you wrong. I'm unsure how they would consider a, but I would \(\it{guess}\) it's not periodic.

Answer 11

This is actually a question from my math hw, but it applies to both math & science :P

Answer 12

On some charts, it might seem periodic; but it is not periodic generally - but the child can also jump differently, if you want to look at it that way.

Answer 13

Okay! Yeah, in the physics area, math and science really go hand in hand.

Answer 14

I know, it would be much better if it were more specific! >:[

Answer 15

Anyway, thank you for your help, whether it be accurate or not it's still appreciated.

Answer 16

You're very welcome! Good luck! :)

Answer 17

This:
"Body temperature normally fluctuates over the day, with the lowest levels around 4 a.m. and the highest in the late afternoon, between 4:00 and 6:00 p.m. (assuming the person sleeps at night and stays awake during the day).[7][9] Therefore, an oral temperature of 37.3 °C (99.1 °F) would, strictly speaking, be a normal, healthy temperature in the afternoon but not in the early morning.[7] An individual's body temperature typically changes by about 0.5 °C (0.9 °F) between its highest and lowest points each day.[7][9]"

from http://en.wikipedia.org/wiki/Human_body_temperature, is one of the things that make me think that it is vaguely periodic. But it's definitely not periodic with varied activity. I wish it was more specific, too, or gave you a source to look at. Take care!
