2. ### Actuarial studies

I already watched it.
3. ### Section I: Multiple Choice

Re: HSC Physics - Exam Paper (download) It states force due to gravity.
4. ### Does God exist?

It is ignorant to assert that there exists no God. Whether people believe there is a God or not, its impact on our lives, whether changing an individual's perspective on the world or provoking intellectual debate cannot simply be ignored. To exist, by definition, is to "live" or have "objective...
5. ### Projectile Motion

Hi Kaido :^)
7. ### How does the law of conservation of momentum apply to the motion of the rocket?

You can also include a brief diagram, including Frocket = -Fgases
8. ### Random Space Qs

Adding to this, if you were to observe a geostationary satellite on Earth, it would appear to stay in a fixed position in the sky (since the periods match), so technically, it is stationary, which satisfies inertial frames
9. ### Random Space Qs

http://galileoandeinstein.physics.virginia.edu/more_stuff/flashlets/mmexpt6.htm You can visually see it here Notice that when you turn the aether winds on, the red component that is moving against the aether wind would have a slight decrease in velocity, and reach the HSM, and thus detector...
10. ### Random Space Qs

Hi Bleh, For 2, the distance between the HSM and the two mirrors are are always constant. What was expected to change was the velocity of the light that traveled with or against the supposed "aether winds". Once the apparatus was rotated through 90 degrees, one of the perpendicular components of...
11. ### Implicit D

For 3u, is implicit differentiation a viable method for finding dx/dy i.e. is it accepted in the HSC
12. ### Parametrics

The straight line y = mx+b meets the parabola x = 2At, y= At^2 in real distinct points P,Q which correspond respectively to the values t = p, t = q a. prove that pq = -b/a I'm sure the solution is really simple, but I can't see it.
13. ### General question on economics essays

What is the HSC standard for the minimum word count that could potentially receive full marks for an essay? And what would that roughly equate to in terms of typed pages/words? thanks.

Re: HSC 2015 4U Marathon I think i misread the locus on my 1st attempt My 2nd attempt (not the most elegant approach..): http://imgur.com/NTfoHbn
17. ### HSC 2015 MX2 Marathon (archive)

Re: HSC 2015 4U Marathon Here's my attempt: http://imgur.com/OsVeIMC --- Find the number of real roots of the equation x^4 + 2x^3 + 8x + 15 = 0 and find the integral values of x between each
18. ### Geometrical applications for complex numbers

If the points A,B,C,D represent the complex numbers α,β,γ,δ respectively and (a) α+γ=β+δ , show that the points are vertices of a parallelogram
19. ### Space syllabus clarification

With the dotpoint "Discuss the issues associated with safe re-entry into the Earth's atmosphere and landing on the Earth's surface", would it specifically be referring to spacecrafts or space shuttles or maybe something else? - making sure I get all the right technicalities for my phys assignment
20. ### Any 2015 engineering students?

Similar situation to mine. My yr 11 cohort had around 20 kids, and by the start of yr 12, only 4 remained. I dropped it as well.
