The "ammending" was just removing 15% of it, though :p

I added the explanation.

It's just writing the equation; you even get a shiny new periodic table to help: 9038Sr --> 9039Y + 0-1e + v + γ That v should have a dash over the top of it, because it's an anti-neutrino. "The Strontium has too many neutrons and is unstable, hence it undergoes beta decay, where a...

u were right the first time. v is not c, since it's an electron, so you have to get the velocity first. λ = h/mv 5.3x10-11 = 6.626x10-34 / (9.109x10-31 x v) v = 6.626x10-34 / (6.626x10-34 x 5.3x10-11) v = 1.372x107ms-1 (3dp) Now v = fλ 1.3725.3x107 = f x 5.3x10-11 f =...

Yes. I did. Honestly, I make so many ridiculous mental slips typing stuff up on this forum... That caused a bit of confusion, too.

The chemistry exam indicates, to me, that the list is quite useless.

You know how when you get an AC generator and graph the power output against time it forms a sine curve? (well, it does!) 3 Phase is using 3 lots of them, all 120o (or 2pi/3 if you like) out of phase, so the power output is more frequently at a peak.

I have official inside info from an admin that it's actually the first step in their [evil] plan to use the broad range of talents possessed by different BoS members studying various things at uni to eventually break away from Australia and form our own rogue state, with the admins as our kings.

Or because they're dull and uncreative.

Do you do chemistry? If so, compare it to bonding in compounds; the stronger they are (eg. ionic bonds stronger than covalent) the more energy you need to use to break them apart (decompose the compound). Or if you don't, think of it as; the binding energy is 'used' (not sure how) to hold...

Teamwork huh?

It doesn't really matter, we'd just be discussing the meaning of words. I just meant that at the end they didn't have any value of the earth through the aether. Remember the experiment was done like 20 years before Einstein's theory, so at the time they didn't really know why there was no...

It was an 'attempt' because they weren't successful to measure the relative velocity of the earth through the aether, for obvious reasons. That dotpoint would consist of a description of the experiment, the reasoning behind it, the null result and reason for the null result.

Warning about 'preliminary' formulas: There are (and this confused me often) a lot of formulas that are VERY useful in the HSC course, that are all located on the preliminary section and may be overlooked. They are: E = F/q. This rearranges to F = qE,which you will need for forces on...

Yes. 5678910

What nosadness is talking about vs what the answers meant:

It doesn't matter, because horizontal and vertical components of velocity are independent (:p) So yes, it may be possible for a human-projectile to achieve an overall initial velocity of greater than 12 metres per second (I'd imagine some long-jumpers achieve greater velocities), but it is...

If you're stationary and shine a light, you see the light moving away from you at c relative to yourself. If you're moving at 100,000m/s in a car and shine a light, you see the light moving away from you at c relative to the car. If you're moving at (c - 1)m/s and shine a light, you see...

Absolutely-ridiculous-bump ... Anyone know anything else about this? I got an interview.

I feel that you'll make a good practitioner of law, then...
