WOW this is so hard!!! First maths question I've done since HSC. I've lost my touch :(

Degree is in my sig. Can't wait for uni (the social life, not the study life) :P

How is my timetable? Does it seem flexible?

Sorry i posted in the wrong thread

How is my timetable?

I've applied for the TFN now, because I didn't know it was needed until today :( Can I still confirm my Uni application and fill out my timetable, then confirm my TFN number later (before the census date)???

Same hahahaha. gg

The photocell wasn't a curveball. It was just insanely stupid to put it in the syllabus as something that cannot include a solar cell as an example.

LOL

Well she had a look at the paper months before it was released, and thus knew the marking guidelines beforehand. I called her and she said solar cells are fine to use and I won't get penalised for it

The head of James Ruse Science confirmed that the solar cell can be used in the description of the photocell. Since she said the solar cell is a type of photocell.

E = V/d You're graphing E on the y-axis and d on the x-axis let E = y and d = x Hence y = V/x where V is constant Therefore it is a hyperbola

That's a hyperbola

The only mark I can possibly get is 1 for mentioning the photoelectric effect :'( There goes the potential raw 90

This is where I got my information from. I can't believe photocells apparently involve the cathode ray tube. Both answers are correct imo. And if a reliable source like Jacaranda is wrong, the HSC markers should accept both answers

This is what the Jacaranda textbook says about photocells, why are solar cells wrong to mention? A photocell is a device that uses the photoelectric effect. These devices include photovoltaic, or solar cells, which convert electromagnetic energy, such as sunlight, into electrical energy. Other...

Never underestimate the power of MX2 aligning! LOL

Realise are you confident the exam will align like this?

Do you still think that deserves 1/3 since the first statement is correct in completing the proof?

How many marks will I lose if I assume it's a straight line? I used alternate angles for angle qbt and angle pat and the other two, then 'proved' it was collinear. Can I get 2/3?
