HAHAh I KNOW AGEREED, she is bringing some history knowledge into it.. haha Is napoleon a fukn moron he would think its gonna go longer? HAHAHA
WERE GETTING TESTED ON PHYSICS wake up

1A
9C
end of discussion for those questions (if your still unsure go back over this thread again)
That's what I wondered in my solutions. That's never happened before, but there was one question that they screwed up because they completely misunderstood the theory of relativity so they just didn't count the question.chensta said:just a question, has there many cases of a question having 2 right answers in the past? if so, then i think most of us are safe, ie the DC battery question:
'when the switch is closed'
could mean, when it is being closed
OR
when it IS closed, as in closed for a while etc
for every radius there is a velocity corrospondant to keep it in orbit. by slowing the velocity the satellite spirals inwards. this sort of thing also comes up in quanta2quarks with electron orbits, however bohrs postualtes say that electrons exist in stable orbits.Dumsum said:OK everyone, for that orbit question (Q4) here is my thinking: Yes, slower speed means larger orbit. But maybe it's not that so much, as larger orbit meaning slower speed. See, for the object to move outwards like that, it would have to GAIN Gravitational Potential Energy. Where would this come from? It said the rocket was fired forward halving speed, so if anything, energy has been lost. I think C (falling back to earth) is the best answer.
Question 15 would be D, right?B.J said:QUESTION 5 100% SURE ANSWER IS C
if you dont believe me check bottom of page 9 of physics context 2 if you got that
Anybody know definitely the answer for 15?
