Must have been pree hard if you are having mixed feelings, Mr Über Nerd Any big mark value qs? Ifso, what on?

It depends on your level of ability and what you want to accomplish Lower level / superficial understanding of dot points: Physics in Focus Mid-range: Jacaranda or Spotlight (Spotlight has some higher end stuff also) Higher level: In2 Physics (love this book! It addresses stuff outside of the...

Confirmed! Principle of relativity = laws of Physics are the same in all inertial frames of reference Special relativity = principle of relativity + speed of light is constant for all observers General relativity = special relativity + Newtons Law of universal Gravitation (essentially) -->...

Remember Planck just derived an equation from the BBR curve which enabled it to be explained. A consequence of his equation was quantisation. There was nothing else that supported his idea of quantisation until Einstein extended it to radiation itself, which could then be used to explain PE Effect

Make sure you mention the role of phonons in overcoming the electrostatic repulsion between electrons

Exclusion of magnetic fields. Quantum pinning / flux trapping is beyond the syllabus, I talked about it with my class as it is a more complete representation of what really happens and why it is not really a repulsion, but a repulsion and attraction, but I stressed that it is BEYOND the...

Do you mean Einsteins contribution to Quantum Theory and its relation to black body radiation?. Ifso: - identify Plancks hypothesis - explain how Einstein extended upon Plancks idea of quantisation and applied quantisation to the radiation field itself - describe how this was able to...

If the bat detected the reflected wave after 0.5s, then that means it must take half that time to travel from the bat towards the tree and the other half of the time to travel back from the tree to the bat. (Sound wave must travel from the bat to the object it reflects off and then back to the...

Thanks to all the students who have contacted me! I still have some places available, both on Saturday and for a weekday lesson. Please contact me asap to reserve a spot for lessons starting 21st September

re: HSC Physics Marathon Archive Here is the projectile motion question which I gave my students for their trial. Only about 10% of students got 4/4

Find attached a sample Band 6 answer to this question, it is labelled as HSC 2012, but it is 2010..

Be careful, as g-force is a measure of Apparent weight/true Weight, therefore, its units are Newton/Newton.. meaning no units. It is just a ratio! if a question is asked 'what is the g-force on John', your answer should be the g-force on Tom is 1, not the g-force is 1g as that does not make sense.

Bump :) pls shoot me an email at madd.fizzycyst@gmail.com if you are interested :)

You have all those trials which I put up for the class, surely there are some skills-based questions in them :)

I don't see how this is really part of the syllabus (unless you are up to the last part of Q2Q already!), but it relates to elastic collisions and the greatest transfer of energy being between particles of similar mass. Seeing as Hydrogen nucleus is simply a proton and it is very similar in mass...

His 2nd explains how the Hydrogen spectrum is produced (transition of electrons) His first and third (combined with centripetal force and Coulombs Law) were able to describe the actual energy levels of the different orbits, so also explain spectral lines in terms of amount energy released...

^^ this F = ma is still relevant, however, the 'a' would not be the acceleration due to gravity (that would be the force acting on the egg whilst it is falling), the 'a' would be the acceleration of the egg when it collides with whatever you are dropping it on. This would depend on the velocity...

(B) As flux = BA, the magnetic field strength is constant, the area of the coil is constant, therefore the flux threading the coil will also be constant. Therefore the ratio will be 1:1

Your teacher was tutoring :P But, yeah.. listen to Habibi, he knows what he is on about :) Just think about the equation that the result(s) are relating to. For example, if you are doing gravitational force, you know that F = Gm1m2/d^2, therefore if you think about the equation of a straight...

So, there are really 2 parts to this question: 1: How did ESTOR lead to reconceptualization of theory of light Think About: - Define Einstein's ESTOR in terms of his 2 postulates - Speed of light before being relative and distance/time being absolute (Newtonian) - Speed of light...
