post some harder questions,

you could take this list, tweek it some, add to,  and come up with very 
hard questions too.

like;

25.  If the Earth rotated on its axis like Uranus, what would the 
seasons be like ?
	How would life be effected when oceans freeze ?
	How would humans migrate ?

.....




please go ahead, no problem, else the HVAC/BJ show, etc ...

Why?

Despite the efforts of some, this group is not for the purpose of a basic
physics tutorial or answering homework questions.

there should be some posts that have a physics or physics related topic 
or content.  I agree with "not having kiddy physics" in here. hard to 
find good stuff, and stuff with equations dosent make it across ascii

This is a physics group; there are separate groups for astronomy.

It is also not a tutorial group at any level.

no cheating,

    perhaps you Starmaker could post your ideas as multiple choice 
questions format.  It would be most interesting perhaps.

39. Did I say

1. no cheating

2. no cheating, Starmaker.

3. no it was typed, not said, and cheating is spelt cheeting.

4. no idea if the answer key you posted is correct-o-mundo or not.



40. some question are very hard, which ones were hard for you?

1. #25 Kepler's third law

2. #26  first truly modern scientist

3. #27 Galileo NOT observe

4. #35 Excape from planets surface of the Apes

You didn't answer the question, how did you get the idea I was cheating?

I said "i wasn't cheating"...now prove how did I 'possibly' cheat? What
is your theory on how I cheated??

Explain, everybody wants to know.

Who is cheating?

You did a cut-and-paste of the Questions...

and I did a cut-and-paste of the Answers:
