EDIT: Beaten by Erutepa... :'(Totally fine for multiple people to have a go at them!
You finished that quicker than I expected, here's another set :) :Set 2A 2.0 kg block (block A) moves to the left at a speed of 8 m/s. It collides with a stationary 4.0 kg block (block b) and rebounds to the right at a speed of 2.0 m/s. What is the speed of block b after the collision?
This one’s more suited to the current year 11 study design (taken from old study design)
VCAA q 8a 2015
“You are provided with four resistors, each of 2.0 Ω. Show how to connect them to produce an effective resistance of 3.0 Ω, using four or fewer resistors. Draw in the space below, so that points A and B are at either end of the effective resistance. Use this symbol for a resistor: Label the resistors in your diagram R1, R2, R3 and R4. If you used fewer resistors, use fewer labels”
In 8b you then calculate the voltage drop across each resistor.
For the 3rd question, I’m directing you straight to question 11 of core studies in the VCAA 2015 exam. This one’s pretty diagram heavy so here’s the link to the exam
question 3no hope of me answering this question, sorry :)
I haven't covered any of that yet unfortunately
This feedback does not seem to be for question 11 of the 2015 physics paper.help w/ q3
for flux, draw the change in magnetic field (passing through the coil) over time
emf is related to the rate of change of flux (pretend the flux graph is f(x) and draw f'(x) )
This feedback does not seem to be for question 11 of the 2015 physics paper.
Question 11 seems to be talking about voltage inputs and outputs of an amplifier.
Sorry! that was supposed to say q 13I just updated my post with question 11, but I shall now try question 13 :)
As we are entering the second half of the epically epic science games, its as good a time as ever to jump into this thread and answering some tough questions.I'm probably not allowed to participate.. I feel it would just be cheating at that point.
Since last weeks questions didn't see to much activity, there won't be a fresh batch of questions this week as I don't want to bombard users with too many questions. So for now, the first group of questions will sit here patiently waiting to be answered.
If you haven't had a go yet at any questions or have only answered some of the questions, now would be a great time to have a crack at them and earn some points. And remember, don't worry about being wrong - if you make an error or get the wrong answer, we can give you some feedback and hopefully guide you to the correct answer!

I will contribute some juicy questions though!
