Q1: A geostationary satellite will appear to be motionless from the Earth, much like the stars. Therefore it is unlikely that they could be distinguished. Q2: Highest precision = lowest error Q3: Induced \, EMF \, \alpha \, - \frac{\Delta \phi }{\Delta t} The higher the voltage in...

I am assessing 3 potential students tomorrow. I want no more than 8 students per group. Contact me if you are a keen student willing to put in the hard yards.

WEBSITE LAUNCHED! http://maddfizzycyst.com UPDATE: (05/02/2012) My classes for 2012 are now full, so I will not be accepting anymore students, unless students leave the class. I have had a number of enquiries for 2012/13 HSC Students who are currently undertaking the preliminary course, due...

Discuss can mean either Give advantages/disadvantages OR give a description. I.e., Discuss BCS Theory requires you to give a description of the theory Assess can mean either give adv/disadv then give your own opinion based on what you have said OR talk about how something has impacted on...

Assess does not always mean pro/con then evaluate. Take Romesh's advice :) With a dot point like this -- always start with Planck, then talk about how Einstein extended upon Planck's hypothesis and then how this extension could be used to explain BBR and evaluate :)

Your teacher is definitely wrong with that statement! The SC itself does not experience a change in flux and in fact more or less "mirror-images" the magnetic field from the SC Perfect diamagnetism, or any diamagnetism for that matter is not studied in the HSC course, neither is flux pinning...

What they want you to know for the HSC is similar to Lenz' Law. Below critical temperature, superconductors are perfect diamagnets. A diamagnet is a material which completely expels any magnetic field lines incident on it. However, Superconductors are a funny type of material, you are correct...

Wave theory suggests that as wavelength decreases, intensity increases infinitely. Intensity is essentially power, or rate of use of energy, so basically infinite energy being used up infinitely quickly. Obvious violation of LOCOE. Planck was a mathematician. He looked at the graph wave theory...

CRT TV: • 3 seperate electron guns, one for each of the colours (Red, Green, Blue) • TV's use electromagnetic deflection rather than electrostatic deflection as it is safer (does not require high voltage) and it has the ability to cover larger surface area • Screen has three different types of...

Conduction band in a SC is an energy band which comes from the atomic valence shell. It is completely empty when temperature = 0. All you need to know for HSC is that energy of electrons in conduction band > energy of electrons in valence band and the greater the amount of electrons in the...

Hertz created different transmitter/receiver combinations which were tuned to different frequencies. The spark jumping across the gap in the transmitter causes electrical current to oscillate back and forth across the gap and along the surface of the rods. The frequency of this oscillation...

If you goto UTS to do engineering, first semester you will do Mathematical Modelling 1, Physical Modelling, Intro to Civil enginnering and some other subject. First semester and probably second semester and so on and so forth you will also meet the Glasshouse Bar and probably be at uni 5...

Personally, I think Q2Q is pretty good, heaps of theory though and not much calculations. I enjoy it most as it is most similar to what I did at university, although I would thoroughly enjoy astrophysics also. Students usually hear the word "Quanta" and think "Awesome! This is the beginnings of...

Quanta to Quarks. It's an excellent continuation from Ideas to Implementation. Some of Q2Q actually used to be in I2I in 2001 iirc

• Hertz used a loop of wire with a tiny gap in it to detect the waves. The electromagnetic waves generated a voltage across the gap that caused a spark to jump across the gap in the detector loop. • To find the speed of the waves, Hertz set up standing waves to measure the wavelength of the...

Without the potential difference, the p-n junction does act like an insulator after it has reached a 'steady state' or 'equilibrium' To answer the second question properly, let me explain a little further =) First consider the process of diffusion. Diffusion is when particles move from areas...

So, we know that a depletion region exists. The electric field runs from the N to P. This depletion region opposes the diffusion of the electrons to the P and holes to the N. So without and applied potential difference, the electric field in the depletion region acts as an insulator as the...

I know this year Baulko are doing Chemistry of Art and Astrophysics, Im pretty sure they do the same each year. Last time I taught a Year 12 JRAHS student, they did Q2Q and Industrial Chem. Im pretty sure they do the same each year also.

That can actually help you though. Say all the tops schools do Quanta to Quarks. In the core section say the students from the top schools average 80%, in the option they average 60% -- that 60% will effectively be 80% =) So yeah, could help =)

So they stuck with being teachers, even though it is so shit? LoL. Seems unrealistic. People always talk shit about their jobs because, well, it is a job... Nobody is meant to like having a job.. We all want to win the lottery and never have to work again. Teaching is basically what the...
