I need help on researching these dot points that are in the copy of the assesment task I attached.

Tank you

we don't do assignments for people...
if you want help, showed that you have done some work yourself first

what i suggest you to is flick through your textbook, alot of the information in there will help you complete your assignment..
also remember there is the charles sturt university website which has invaluble information..for hsc subjects..
either then that.. the assignment that has been given to you is pretty straight forward. just think as each dot point as a normal comprehension question you might get in english...
note google is your FRIEND ...USE IT!

My main problem with the assingment is the words at the start of the sentense.

Like gather, identify, process etc. I looked up the definitions but Im not sure. Basicly each dot point is a question... yes? So to answer the 2nd dot point it will be similar to this:
basicly I need to say that microchips and microprocessors lead to the invention of computers and hence people now leave a lot of difficult calculations to computers and save time by this to do something else. Also computers now lead to a lot of unemployment due to computers taking jobs.

that is correct!
but since it says that you have to identify data sources, that would mean you have to find evidence for your response....

many textbooks should have page reference for each dot pt in the syllabus.

mm some minor corrections:
>> invention of computers <<
small and powerful computers AND rather-big but extremely powerful supercomputers
there were computers before transistors existed, they (or it if there's only 1 in the world..) used vacuum tubes.. I think there was that kind of computer...

>>Also computers now lead to a lot of unemployment due to computers taking jobs.<<
should also mention a shift in employment type

---
also, allows things to
-> be light and portable
-> consume minimal electricity (and use battery)

you might also consider this: allows portable radios and also created new music genres

effects dont need to be good... computers create health problems (in eyes, hand, back [due to sitting position though])
game consoles like PS2 etc make ppl less social

for dot point 3 I need to say something similar to this:
I need to talk about how super conductors work and then apply it to the maglev train, say that extremely strong magnetic fields lift up the train, which has zero friction between tracks and "weels" and hence can do hing speeds.

Or do I just have to talk about how maglev train works and explaying everything

for dot point 4 I need to say this:
for computers I need to talk about magnetic resonance imaging also motors and generators could be made with a weight of about one tenth that of conventional devices for the same output expand on that a bit more. And for transmittion over power lines I would say that it would have basicly no enery loss when transmitting over long distances

yes, but im not sure if magnetic resnance imaging is really computer-related.
MRI does "appear" in my textbook (guess we're using the same 1..) and doe use computer to process the images but it's not the computer that takes advantage of sperconductivity.

the speed of current processors is limited by the heat produced and by the transmission speed between two pts on the processor or the computer as a whole. supecond film can be used as conductor. supercond material of course generate almost no heat (as it has virtually no resistance). supercond electronic components have achieved switching times of 9 picoseconds... not sure what this means haha.. just copied from the book
And now here's from Excel book (some1 posted a PDF version of the book in the Resources section.. how cruel!! but good for me so I dont need to buy)
"Superconducting switching devices are being tested for use in high-speed computers since they can operate at speeds up to ten times the speed of an
equivalent semiconductor switch."

>> And for transmittion over power lines I would say that it would have basicly no enery loss when transmitting over long distances <<
true, but since the dot pt says "discuss possible applications" you should say that it's possible but not very practical just yet. u need to keep the temp low for the matter to bahave as a supercond.. research is being done to find supercond materials with higher critical temp (the temp at which the supercond characteristics are observed)
and unfortunately those which have high critic temp [which is still around minus 150 celcius haha.. but it's not technically troublesome since u can put flowing cheap liquid nitrogen around the supercond to get it to that temp and it will pretty much stays the same since supercond doesnt emit significant heat] are ceramics, which are brittle and cant be mad into thin wires.

>> Or do I just have to talk about how maglev train works and explaying everything <<
mm if u explain everything dont u also explain the supercond stuff?
also mentions (or perhaps explain.. but maybe not since ur scanned pic says it's only 1 A4 page) ifthat the Meissner effect is what causes the magnet to be levitated.

good luck..
btw my holiday assignment doesnt limit the of pages :D

apparently i have a class assignment on that.. except the first point...
just did it today..
here's mine. but pls make sure you understand what you read and check with the textbook or teacher if you havent.. otherwise it won't be a lot of use copying stuff...
and sorry to give u too much reading... :D

(attachment is now removed to ensure anonymity :p)

I checked that out tnx. Obviously Im not oging to copy it caz the teacher will ask questions and I need to answer them and without understanding this I will not be able to.

I dont understands the 1st dot point im my assaimgment.

oo i just re-read ur assignment and it's A4 double-sided... now that make sense coz 1 A4 page is really short for 4 dot pts considering it's a research assignment :p

i didnt know u had the other 3 pts on quarks... but they are common stuff and aredefinitely in ur textbook.. and if u go to the Resources section of boredofstudies.org there should be some notes as well...

regarding the first pts on the political thing:
yeah thats one of those weird dot pts u just have to bear with..
if u use the jacaranda textbook theres a bit about that on page 201, physics fact.

basically what scientists say to the public (and how interpret the results to some extent) is influenced by the social and political conditions at the time.

pl(anck) and ein(stein) were firm friends and lived in germany, with hitler and during the anti-semitism (i think it's anti-jews). those ppl were opposed to relativity and the quantum theory just becoz they come from jewish ppl [my textbook doesnt mention pl is also jewish but i imagine he is].
ein, who was jewish, migrated to the US during 1930s.
pl continued his academic career in berlin. he & his friends were threatened etc and that might be 1 of the reasons why he initially disagreed with the quantum theory.

ein was a pacifist but he later compromised his ideals with his support for the development of atomic bomb... (maybe it was to attack germany? im really bad at history and my textbook doesnt say more about that)

EDIT: in that site u told me there're some articles on einstein and pacifism... u might get somthing on that first dot pt...
and apparently ein was quite brave.. "Einstein ignored warnings from worried friends to keep his own head down, and appeared publicly at the annual rally of the 'No More War' movement in Berlin." [quote from one of those articles]
reading from my textbook i tought he just flew to US to avoid risks.

do i need to talk about how Plank refused to help Germany in creation of weapons or Einstein started the idea about the manhattan project

You can try this:
http://www.hsc.csu.edu.au/physics/core/implementation/9_4_2/942net.html#net13
good luck.

BTW with the effects of transistors on society, you can talk about how easy it is now to find informatio on the net, and the net exists because there are a large amount of computer users and computers rely on transistors ^_^
to add depth, you can also make a detailed description on 1 <u>particular</u> use of microprocessor. for example, microchip can be used in car to control fuel consumption, and this would lead to reduced fuel usage and reduced pollution and hence better public health.
