not sure if this is correct, using this formula a = v^2/r i got 425m but it dosn't really sound right, whats the correct answer ?

Hehe, this one of those pracs superhubert is talking bout, this proves the motor effect perfectly :D take a look:

To be used as a motor: You connect the motors electric terminals to a power source and then it spins (therfore this is a motor) To be used as a generator: You connect a light bulb to the power input terminals of a motor and manually turn the motor and wallah, the light bulb lights up...

Im gonna fly Jets (aeronautical eng, syd uni or adfa) :spaceshp:

LoL, yeah Alexz is right. It was actually gallelio that droped the ball from top of a moving ship.

LoL man how can u not like motors & Gen topic ? Topics with alot of pracs rule. My option (age of silicon) and motors and generators had alot of pracs in them. The best prac we have done this year i would say is when we were given an assignment to build a motor in Motors and Generators...

Well does any one believe in the saying "No mater how good you are there is always some one out der better than you." :graduate: :chainsaw:

LoL, How old is he ? Our physics teacher sometimes brags about it but our class has thier doubts. We also caught him a couple of times flirtin with the biology teacher. Teachers set good examples.

Im just leaving a 5% error margin u know just in case of misinterputing the question or forget to put certain units after numbers etc. In actual fact im aiming for 100 but im also puttin a tiny bit of reality to it (Just in case). It would be great if in the end we could find out our RAW...

well could this stand for an arguement as a good example ? Ok say i wanna fly a jet from point A to B wich is 1Km long. I could either fly thru air (gas state) or water (liquid state) one would work the other wouldn't Now can we compare that to transfering electricity. I wanna send...

Nup, I never had a tutor and never will i rely on my motivation entirely. If i wanna learn something i will and if i dont i wont. Tutors cant change that. Good aim for 100 so i can take u as competition :cool:

Yeah i think it should be coz we do have changed properties. Just the same way that gas and solids have different properties. Mag fields can no longer penetrate and electrons expreience no resistance, so basicly its a change of state.

Do u guys know where i can get the 4 Unit paper u guys just did ? I wanna check it out but every 1 i know does 3 Unit.

Poll ure thoughts ! My Fav to Least Fav is : -Age Of Silicon (Fav) -Motors & Generators -Space -From Ideas to Implementation (Least Fav)

Dado im hoping that can be done for chem, for physics i know it can be done but im gonna give it a shot at chem.

Im aiming for 95 + raw mark in physics. Think u can beat that ?

Alrite any one gotta anything to say bout AOS ? Im doing AOS but school dosn't have the required resources to play with amp circuts so i run a comp simulation and it works great. Does anyone actually have the resources at thier school to test out the amp circuts ?

What the Hell ?? They downsized the Physics course ? I just looked at the modification and i cant believe it. I dont know how everyone else did but we actually finished the entire course including the option topic EARLY. We had like 6 weeks just to do practice questions and revisions...

Get the syllabuse paper for physics, go thorigh em and tick what ever u can properly explain/understand. What ever u cant tick make sure ure able to by tuesday.

Question 17 was actually part of the course. You know how in software when ever u gonna enter a development stage they say "whats the most important thing u gotta consider ?" and then the answer would be always to "solve the initial problem". Well in this case we got a photographer who...
