I just made a new topic on the extended response at the back, lets go there for discussions on that.

 

[sfer]

On the voltmeter question was it 5.2 or 0.52?

5.2, because it was plugged into the 20V plug and not the 2V one

I put in that jellies might represent fossils and because there are no jellies at the bottom layer, therefore there are no fossils found. I thought of writing down that the layer must've been where fossils don't form e.g. fast-flowing rivers but I couldn't be bothered. I regret that now

Same, I wrote an analogy for the question concerning the jelly and stated the model represents the theory of superposition. I stated that the layer of jelly (rock) did not contain any lollies (fossils) because there were no organisms during that period since it was the oldest (at the bottom) . E.g. No fossils were found in the oldest layer of rock because organisms did not date back to that time.

easy but in the extended response i wrote disadvantages mainly for environmental impacts of alternative energy. though impacts can be good or bad. so i don't think i did too bad.

was it meant to be in essay format? because i did mine in dot point. crap.

also i stuffed up the question on the smallest unit of an element, i put electrons and i think its atom.

any help?

I think dot point is fine. You won't lose marks on that probably but markers prefer an essay-like structure so it would have put them in a better mood. But don't worry.

I put electrons as the smallest unit as well. I doubt it's atom although it could be.

I put 6 V.

Im extremley sure it was 6. I remember that question clear as day. The power was to the Negative and to the 20, and it showed 6 cause they went up at .5 intervals...

What was the answer to the last 7 mark extended response?
Was it the impact of fossil fuels or renewable energy sources?
I got confused =/

I put they don't release CO₂, CO, S or other air pollutants so they don't affect global warming or acid rain. The solar panels are small and can be installed on homes (don't need power plant). Also solar and wind are renewable.

For disadvantages; nuclear accidents kill lots of dudes, wind is expensive and requires lots of space and only work when there's wind, solar is expensive and only work when the sun is out.

Oh shit, I got it wrong.

 

[mirakon]

5.2, because it was plugged into the 20V plug and not the 2V one

Did you use the right scale? I'm sorry but I think you're wrong. I'm quite sure it's 6V.

Its 6V.

For the response i wrote about cost and taking materials out of the ground etc. Think thats good enough for a good mark?

 

[nae_13]

i did 6V as well.. the wire was on the 20V one

 

[mirakon]

wind is expensive and requires lots of space and only work when there's wind, solar is expensive and only work when the sun is out.

I'm not sure this entirely relates to the question as it asked for environmental, not economic or financial impact..... I'm probably wrong though so don't get stressed.

What was the answer for Q6, the mobile phones transmission one? o__O

I'm having conflicting answers with Official.

 

[sfer]

Its 6V.

Yeah, 6V, 5.2V, whatever it was - I was just choosing the answer from those...

 

[Official]

The answer is 6V

 

[sfer]

For the response i wrote about cost and taking materials out of the ground etc. Think thats good enough for a good mark?

Cost isn't really an environmental factor, though.

Sorry please elaborate, can't remember that one..

Uhh if i remember correctly it was Electromagnetic, cause light meant visible light.

That was like a trick question, mann. I was thinking electron but I ended up putting atom.

What about the one with the iron strip and corrosion? Which one made sure it was only water? I put 3 and 4.
