what are the differences in terms of the role in jobs. i hear chemical engineer is more focused on physics whereas industrial is concerned with chemistry. which one has more jobs and are the pays similar?

i am wondering what the competition is like for the students that major in vision wanting to transfer into optometry. what is it like when you were going through the first year? did you make the transfer? and if not what do you do now?

their both bloody easy in my opinion. Engineering studies is the hard one, stfu all of you's

the sulfate content experiment in lawn fertiliser. pretty simple now since i did my method.

pm'ed you

is all of the lawn fertiliser soluble in warm distilled water. if its not then what remainder particles are floating around and how should i improve the method then

I forgot to mention, if in your class you are top in ur 4unit, 3unit or close, but your not doing that well, then you can go for it... because i think (not sure about this one) if you are rank 1, and you sit the test and you also come in rank 1, its possible ur scaling would be good for your...

lol it's usually default 100 because your in 4unit :), its assumed your band 6 but it doesn't count. 3unit = (2units for HSC), 4unit = (2units for HSC) = 4units for HSC

Your UAI is based on scaling, you cannot say that just because someone has done 4unit it gets them this mark. It depends on a lot of factors you need to play with. Not to mention your schools contribution, its standing and your standing in the course. If you are generally the one that does...

lol im studying english and doing maths i cant do this its too conflicting xD ill post it up if i ever get the solution.

oh you're talking about that, yea the birds horizontal component is different to the rocks. They are two different events. Is that what you mean?

the rock does not reach double the height exactly on top of the pole, because it is aimed at the pole, it will draw a parabolic motion and the maximum height is after the pole, and hitting the bird at the same height as the pole. sorry i mean touching, test writters don't like to be cruel :D

Horizontal components never vary? they are constant, same with downwards component which is gravity. Horizontal and vertical component do not effect each other and can be treated as two seperate terms.

And, the question is possible to do, a friend of mine got a value out althought it was incorrect. The answer derives from using a few variables.

That is the whole question. Honest to god i can photocopy u the page and link you it. My maths teacher said you can get it from first principle, working out is about 2-3 pages, his a capable maths teacher, teaching me in 4unit atm. He hasn't told me his progress due to the fact that he hasnt had...

The answer is 12.1m/s oO, err... what did you get? lol

I need help with this Projectile Motion question: A stone is thrown so that it will hit a bird at the top of a pole. However, at the instant the stone is thrown, the bird flies away in a horizontal straight line at a speed of 10ms^-1. The stone reaches a height double that of the pole and, in...

------------------------------------------------------------------------ Thanks, i kinda figured that out, but when i took that into account, things didn't work out as i got Q = 200 - 100e(-0.03t) , in this case that is incorrect according to the solution. But you do make a good point, that's...

Here is the working= we know that rate of inflow is 3L and 2g per litre, hence 6grams total inflow. Outflow is Q/100 x 3 (which means Q unit of salt per litre is following out) because, in the tank it contains 100L, for now Q is the amount of salt at any time. In addition 3Litres is...

Nvm i think i figured it out, initiall t=0 Q=300 (i stopped after that because you can't logbase e a negative number) so if you continue it will become evident that you just use your logarithm rules. Damn sunday night and im doing maths god, it's annoying.
