It says that "the rocket's engines are fired continuously" as you go further away from the Earth. Consider: E=1/2 mv2 and F=ma As the rocket is flying: m decreases and hence, a increases as F should be relatively constant (based on F=ma). As a is increasing, and already positive: v also...

The answer is A.

They're called persistent currents, not meissner surface currents.

it's a general curve that has half above, half below - imagine the type of curve you get from Excel.

To me, they have been the same thing. Pretty much the difference is the sign. ΔH<0 is exothermic, ΔH>0 is endothermic. q<0 is endothermic, q>0 is exothermic. For HSC, I recommend that you use ΔH because that's what's on the formula sheet and what you are expected to use, not q.

Met this guy at uni before, pretty cool guy, and would recommend.

In an earlier post, I clearly showed that I wasn't using Gine Rinehart as a generalisation for all rich people - it was a direct response to the fact that nerdasdasd generalised and gave an impression that all rich people work hard, which is very questionable. In future, consider reading the...

The regular streams aren't very hard - advanced is significantly harder.

With such an immense amount of money to begin with, that's very questionable - particularly because she chose the mining industry. If she did something that was more useful such as invent something, it would be a completely different story. In that case, you could say it was "not something...

My response was to nerdasdasd and referring to the fact that the rich aren't rich because they worked hard - essentially, what you have said is what I just said to nerdasdasd and I never said that anyone is entitled to anything.

Wrong. While true for some, many did not "build their way up". For example, Gina Rinehart inherited the Hancock Prospecting company and built it up from there but that certainly doesn't mean she was self-made. Money makes money. Worked hard is completely bullshit - there is only so much you can...

Awkward moment when I'm turning 19 in a couple of days and still can't grow a beard.

I did know his work history as a food chemist in QA/QC so they can't mark you down for that. Generally, if your work is at least mildly amusing to read, you will get a good mark. Only recently, at uni, I put a pic of a hot babe in the body of a paper I wrote and got 90.

You can't skip this dot point - it's quite common and "making it up" will almost certainly get you a straight 0. If I remember correctly, for the scientist question, I did my teacher in the trial or one of the assessments.

To be honest, there's about the same amount/level of maths and it's not harder - about the same difficulty all round.

You also need to consider geometry. If it's symmetric like CO2 and CF4, even with differences in electronegativity, it is non-polar.

None in first year, 12 cp in second year, 24 cp in third year. And when I saw first/second/third, I mean 1XXX, 2XXX, and 3XXX units.

That's pretty horrible advice. Just because you struggled in one course, doesn't mean you will struggle is another course. Especially if it is in a different field.

The chaplaincy program was junk.

Changing ANY unit of study will force you to get a new timetable.
