Yep, agreed again!vizman said:agreed.![]()
I love that feeling too.~shinigami~ said:Physics may not be my favourite subject but I love the feeling of satisfaction when I can figure out a problem.![]()

I dread every lesson
probably cos of my crap teacher
To be fair, you answered the question, so anything you write after that pretty much doesnt matter. A lot of the teachers i know will stop reading your answer once you've written enough to get the full marks.ice ken said:i LUV physics but i HATEEEEEEEEEEEEEEEEEEEEEEEEEEEE the teacher. he is such a fag all of us learn by ourselves. even all the teachers know he is crap we tell our maths,esl and chem teacher. they said they know they know. and he marks shit i did a question in a test on purpose still correct. :mad1: . and we all laugh wen i get it bak other teachers too. it was this question in phyiscs test.
1.why are geostationary satellites always launched into an equitorial orbit in a west-east direction, irrespective of whether or not they are to be geostationary?apply similar reasoning to suggest another reason why launch sites near the equator are preferred. i exactly wrote this.
Satellites are preferably launched at the equator in a west to east direction because this is the easiest and most economical way of launching a satellite. The earth rotates quicker at the equator, therefore the satellite receives a greater initial speed. The satellite is launched west to east due to the fact that this is the way that the earth rotates, therefore if it is launched in this way it will travel with the earths spin, hence providing it with extra speed. This can be explained using DeMoivre’s theorem (|z|cisq)<sup>n</sup>= |z|<sup> n</sup>cisnq, but first you would need to equate the imaginary and real parts together i.e. find the n<sup>th </sup>roots of unity. After finding this you would need to display this on an Argand diagram, showing why satellites would be preferably launched at the equator. An alternative way to show this would be to show all third degree polynomials in polar form.
this was a maths explanation he gave me 8/8 for this question. class mates were LOL. he is only at this school cause he is the rowing coach and there is no teacher that understands physics. a funnier situation was when in yr 11 he gave 2 marks to my friend for a question he told us to correct in the test cause he wrote it wrong friend wrote nothing "just corrected a symbol" 2/2
Apparently a lot more maths in pure physics.chocolate_lover said:What's the difference between the two??
Does that mean less of the non-maths things?SoulSearcher said:Apparently a lot more maths in pure physics.

That's actually a good thing for me, since i suck at maths.timobr0 said:Yeah they "dumbed down" the HSC Physics course. Took out all the maths and added all the social and ethical, and history crap........
yeah i know - its now another subject like english, where you can get the answer right, but worded it slightly different to the ideal answer and they deduct marks from you. :burn:timobr0 said:Yeah they "dumbed down" the HSC Physics course.

Damnit, I think I know who is responsible for the crappy changes in the syllabus if I am correct, I much prefer maths, but you need an exact answer to be correct. On the other hand, the accuracy of your answer to the "social and ethical, and history crap" will reflect on how much marks you will recieve.timobr0 said:Yeah they "dumbed down" the HSC Physics course.
