    General Thoughts: Physics

    Also, the electron is not instantaneously deflected by the electric field as it shows for a large portion of the electron's path to be undeflected whilst in an electric field. Also, it shows linear motion, however it should curve out a parabolic path towards the positive plate.

    General Thoughts: Physics

    Model x assumes a uniform gravitational field, where acceleration due to gravity is assumed to be constant for every point in Earth's gravitational field (9.8m/s^2) I calculated the value of g at an altitude of 200km above the Earth's surface using g = GM/r^2 which turned out to be around...

    Section I: Multiple Choice

    The answer is 40. Find expressions for sinx and cosx, and divide to find tanx. The angle turned out to be 40

    HSC Physics Marathon 2013-2015 Archive

    re: HSC Physics Marathon Archive The theory of relativity states that the laws of physics are the same for all inertial frames of reference; it is impossible to conduct a physical experiment within an inertial frame without reference to an external point. The principle of special relativity...

    General Thoughts: Mathematics Extension 1

    its known that sinx/x = 1 so lim x-> 3 1/(x+2) = 1/5
