Induction motors..
wat do u have to about induction motors for HSC
syllabus only asks for
- main features of an AC electric motor
- perform investigation to demonstrate the principle of AC induction motor
do i have to learn induction motor fully?
how bout squirrel cage???
so...
u write stuff like this?
secondary coil was connected to galvanometer
and primary coil was connected to power suplly...
i cant write a good result -_-
when we did this
we placed primary coil into the secondary coil
( primary coil has smaller coil .. so step up transformer )
the needle...
perform an investigation to model the structure of a transformer to demonstrate how secondary voltage is produced
do you talk about how did u make ur transformer -_-
i need help!!
We doing a research in school atm
i am stuck on these questions and i need help please
Q1. How does the defect in CFTR contribute to the symptoms of cystic fibrosis?
Q2. What is the link between genes and a healthy organism?
Q3. What is the relationship between gene expression and proteins...
Outline the processes used to produce transgenic species and include examples of this process and reasons for its use
keyword is outline..
so you dont have to know the diagrams ???

thank you!!
- perform an investigation to help distinguish between
non-inertial and inertial frames of reference.
i never did experiment on this point at class -_-
can you guys help me please!!
thank you all!!
Q. In your Physics course you have performed a first-hand investigation to demonstrate the motor effect. Explain how your results demonstrated that effect (4mark)
can any1 please give me 4 mark response.!!
thank you very much!!
Hey guys..
got my mid course exam tommorow-_-
and i wanna know something.. very urgent!
u know if u look at syllabus..
some points says
-solve problems .... using v=u+at for example ^^
u know there are lots of formulas
like a=t-mg/m centripetal force formula etc...
but syllabus...
umm i was looking past paper.. and i saw this question
Question 19 (4 marks)
In 1970 NASA launched Apollo 13, their third mission planned to land humans on the Moon. Half-way to the Moon a huge explosion crippled the spacecraft. The only way home for the astronauts was to fly around the back...
I was studying % revising einstein...
and i read some info on mechanical and optic experiment
1>
'Principle of relativity was recognised only as an mechanical effect. This was because the aether model implied that the princle of relativity did not hold for optical experiment'
what is this...
Sup all!!!
i need help on language..
Can u guys plz help me

Hi guyz ^^
i was writing my syllabus notes..
and i dont get this one point
Production of Material
Section5 Nuclear chemistry provides a range of materials
Students:
- Process information from secondary sources to describe recent discoveries of elelments..
wat elements?? -_- can any1 help...
i heard this syllabus point is very important and last year HSC had 7mark based question on this point.. so i wanna know more but it's hard -_-;;
-analyse information from secondary sources to summarise the industrial origins of sulfur dioxide and oxides of nitrogen and evaluate reasons for...
Can anyone help me please^^
Q1. What is e.m.f?
Q2.Faraday's Law of Induction states 'the induced emf in a circuit is equal in magnitude to the rate at which the magnetic flux through the circuit is chaning with time' what does this mean?
Q3. How is this LAW (above) relates to the result...
