    Repeating HSC (Weird scenario)

    Hey everyone, I completed the HSC in 2006 and did very well - got a UAI of 97.55. I thought at this time I knew what I wanted to do and picked Computer Science at UNSW. During the first semester, I realised how boring the rest of my life would be if i stayed there so i decided to transfer to...

    Transfer from another UTS course to B Vis Comm

    Hi, I'm currently doing a BSci IT at UTS (2nd year) and find it boring and unsatisfying as hell... I seriously regret doing this course, and I regret thinking that I wanted to do anything to do with IT in general. I wish to eventually transfer into B Vis Comm at UTS, but since I've already...

    UAC offer letter

    Hi Im not sure of something. Do you need to sign and send the UAC letter because in the booklet that came with the offer letter it says "DO NOT SEND YOUR ACCEPTANCE OF OFFER TO UAC". But ive accepted online and enrolled and etc, but just out of curiousity logged in to view my offers and my...

    induction inequality question

    Im not sure if i did this question correctly, could somebody check for me. Thanks. If u1 = 1 and un = root(2un-1) for n >= 2 a) Show that un < 2 for n >= 1. Step 1. If n = 1, u1 = 1 ***< 2 therefore true for n = 1. Step 2. Assuming true for n = k, uk = root(2uk-1) < 2 Step 3...

    induction query

    Ok theres a question, im not sure if what i did was right.. well i think it is..but anyway its best to check hehe. If you have an induction question such as the following: If u1 = 5, u2 = 11, and un = 4un-1 - 3un-2 for n >= 3, show that un = 2 + 3n Is it ok to do the following: 1...

    inequalities question

    Is it ok to do this: E.g. Show (a2 – b2)(c2 – d2) <= (ac2 – bd2) Working backwards: (a2 – b2) (c2 – d2) <= (ac2 – bd2) a2c2 - a2d2 - b2c2 + b2d2 <= a2c2 – 2abcd + b2d2 - a2d2 - b2c2 <= - 2abcd a2d2 + b2c2 >= 2abcd a2d2 - 2abcd + b2c2 >= 0 (ad – bc)2 >= 0 Then what I write on my...

    projectile question

    I'm having trouble getting the answer i the back of the book.. If anyone has done this question, could they please check for me> It's Cambrdige Exercise 7.3 Q11b The answer says 10(root2 - 1) ms-1, but i get 5(2root2 - 3) ms-1... Yeah ive done the question twice..keep getting that...

    mechanics question

    Im having some trouble with the second question in the exericse 7.2 from cambridge. I can get the distance, but not the time (can't seem to be able to integrate the acceleration in terms of t...) 2. A particle is moving vertically downward in a medium which exerts a resistence to the...

    attendance

    Im really worried now about my attendance.. Ive counted.. (approximated) that ive had 21 days off this term... maybe about 10-15 days last term, and maybe 6-8 days in terms 1 and 2 (although my report says 4) So adding it up gives maximum of 44 and minimum of 37 days. I heard that 85% is the...

    stupid SHM signs

    For this question: A body is vibrating in simple harmonic motion, the period being 12 seconds and the amplitude 10 cm. What is the velocity and acceleration of the body when the displacement is 6 cm. x'2 = n2(a2 - x2 12=2pi/n n = pi/6 a = 10 so when x = 6, x'2 = pi2/36(100 - 36)...

    neutrinos

    Im a bit confused as to why neutrinos were necessary in terms of what jacaranda states. They explain the need for neutrinos in terms of the varying energies exhibited by the beta particles emitted during the beta decay process. Excel explains it in terms of a break down in the conservation of...

    volume questions (cross section thing)

    The base of a particular solid is x2 + y2 = 4. Find the volume of the solid if every cross-section perpendicular to the x-axis is a parabolic segment with axis of symmetry passing through the x-axis and height the length of its base. This question was so hard..took me so long and i got 2pi...

    volume enquiry

    For this question: {(x,y): 0<=x<=2, 0<=y<=2x-x2} about the y-axis The method the book introduces in its example, does it by having two radii things, x1 and x2. My first solution is: ∆V ≈ (πx22 - πx12)∆y = π(x22 - x12)∆y = π(x2 - x1)(x2 + x1)∆y y = 2x - x2 x2 - 2x + y = 0 x1...

    some questions

    Ok there a question that i dont get: 5. If the atoms in a sample of hydrogen were in the state n = 5, how many differnent spectral lines could be produced by the gas as the electrons returned to the ground state. I was confused with this question and my girlfriend pointed out that hydrogen...

    projectile motion

    Could somebody please check this, i think the answer in the book is wrong. 2. A cricketer can throw a ball 40 m vertically upwards. What is his maximum throwing range on a flat cricket field. Let V represent the initial velocity. Maximum range occurs when @ = 45 degrees so, uy =...

    interference and diffraction - braggs experiment

    In my edition of jacaranda hsc physics (edition 1), there are detailed explinations of diffraction and interference leading up to the Braggs experiment. It is necessary to know this (in such great detail) for the HSC? Also is it necessary to know the formula, I = vqAp? ------- Also i...
