bump.

there is a subject called modern history? did not know this.

question a) is different to question b) the thing on the right on the diagram is the star.

a) you didn't answer the question, it's only asking the best trajectory from earth to mars and where is should intercept with mars' orbit. b) just answer the three points in the question. - What letter would it be best to use the slingshot effect at - What direction should it approach from -...

Here are some more perceptive questions. a) A satellite was launched from Earth to Mars. What is the optimal point of interception of the satellite with mars' orbit in relation to where it was originally launched from earth to ensure minimal fuel is required for the journey? (2 marks) b) A...

No, he is saying that you don't need to talk about EMS in a question that asks about application of superconductors because they don't utilise superconductors, rather conventional electromagnets.

for part 2. they are correct but the question says "during its launch into a stable orbit"

A PNP transistor is used to either amplify a signal, act as a switch to stop current flow, or as a rectifier to ensure unidirectional current. The conjunction of 2 diodes (insert diagram of Emittor, Base and Collector and the 2 circuits) can be biased appropriately to perform each these...

lol shonga just realised :P the three I was going to say are (spoiler alert highlight below) g-force = apparent weight/true weight. Apparent weight is the sum of the contact forces acting on a body, and true weight is the normal force on the body when it is stationary on the earth's surface -...

I want MOAR. what is apparent and true weight?

- Overall HSC mark determines the performance band - The HSC exam determines half of your overall HSC mark for a subject, with the internals providing the other 50%. The HSC markers inspect the exam and decide on an appropriate mark one should recieve in an exam to recieve a certain mark/band...

Define g-force (1 mark) Outline THREE safety mechanisms used within a rocket during its launch into a stable orbit to protect the astronaut from excessive g-forces. (3 marks)

do we need to know how to draw PNP and NPN diodes for physics?

it looks a wee bit short for a 7 marker tbh. i don't do that option so i cant say whether its good or not sorry

yep sorry that's correct.

ok ive got this gimme a sec. Firstly they rinsed with water instead of acid. This will mean that the molarity of acid in the burette will be lower than expected as it has been diluted. (i.e. pH4 instead of 3) Pipette rinse is fine Conical flask rinse will result in the solution having more OH...

That's a difficult one, it's either A or D but I'm guessing you already got this far. (because the Town sewage drastically increases BOD due to organic material going into the water) I would go with A because rock discharge could increase TDS and also chemicals changing the pH. The other...

I think you have quite a good chance of getting your aim :) the average atar is 68-69 and you are on or above average in most subjects. Standard english might pull you down a little bit, but at the moment I think you may be looking at a 68-70 atar.

yeh its a trade off between being stingy and buying a cheap car that could break or buying a decent car and hoping to get resell value at the end of next year.
