Question

Calculate the orbital speed of each planet by dividing the distance it travels in its orbit by the period. The units of your answer should be AU/year. Record your answer in the table.

Answer 1

Sounds more like a physics question.

Answer 2

Yup, close and repost in physics.

Answer 3

I tried this already but still no help

Answer 4

Posting a physics question in the biology section won't help either. You can try posting it again in physics when there are more people online there.

Answer 5

Okay well thanks.

Answer 6

by the way how can you calculate the speed when no information is given about the distance the planets travel? or the period?

Answer 7

That was the reason I was asking for help because I don't know either it never said this stuff it just gave me a table and that's it so I don't know how to answer it

Answer 8

You should add this table to you question

Answer 9

I did on the Physics post and no one gave me an answer

Answer 10

If someone could just help or give me a way to answer I'll be able to do it but I have no clue.

Answer 11

This question should contain information about distance and period. If not you cannot answer it.

Answer 12

Question already tells how to calculate it... divide the distance the planets travel in its orbit by the period

Answer 13

Could you give an example? Maybe I can find something but it would help if I knew how to do it.

Answer 14

\[Speed = \frac{distance }{ time }\]

Lets say the planet travels 400,000 m in 1 hour
The distance is 400,000m and the time is 1 hour = 3600 sec (60*60)

if we divide the distance by the time you would get:\[\frac{ 400,000 }{ 3600 }=111.1111 m/s\]
Last thing to do is convert to AU/year
1 Astronomical Unit / year = 4 740.57172 m/s
Our planet's speed is 111.1111 m/s
Now divide 111.1111 by 4740.57172 = 0.02343833329 AU/year

Thank you
