bohr and de broglie. just talk about how these two work lead into begining of using only uantum mechanics /physics to think about the atomic structure

pretty easy i mean besides one that i went blank on only a 2 marker tho so hopeing for 80s raw mark so should be good

lol finish tomorroww WOOOOOOOOOOOOOOOOO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1

Heat: The considerable kinetic and potential energy possessed by an orbiting spacecraft must be lost during re-entry. As the atmosphere decelerates the spacecraft, the energy is converted into a great deal of heat. This heat must be tolerated and/or minimised. The heat can be tolerated by using...

physics is interesting IF U UNDERSTAND IT. seriously if u dont then well i can see how it could be boring. But since i do understand da physics i find it hella interesting although seems to have so much historical and theory stuff for my liking needs more maths

nope not really but once i finally finsih the transition will occur lol :P

yea thats wrong

ok pretty much conduction band is the level where an electron will be free from the atom thus able to move freely amongst crytal. p and n type refer to http://community.boredofstudies.org/showthread.php?t=190299 go to my post then go to website lol

dont know but chadwick and fermi's uestion thing may not be a dotpoint but come on u should be able to do that if u understand what they did

nope only in optional

yeah essentially physics is just concepts. U learn and understand these its not hard to build on them. I mean i guess not that much to remember if u know the concepts which are developed throughtout each of the topics.

lol i know how u feel PEOPLE READ THE UESTION CAREFULLY and think irregardless of logic what it is saying

for number one difference occurs within the void area. http://hyperphysics.phy-astr.gsu.edu/hbase/Solids/dope.html scroll down it just means for n type they gain essentially another level to accept electrons for p type another level to accept holes

yea but its the astronaut looking at the clock on earth not an observer on earth

from his posts seems like he is doing hsc this year so i mean wtf????

first thing yes second no: within a motor a current flows and has an emf which repels it from the magnetic field in which it lies thus turning it or something close to that lol third no : mainly generators use kinectic energy to turn the rotor such as steam turning large wheel which then turns...

T=nBIACos theta

i dont know about the hsc. (DAMNIT U SHOULD HAVE PUT AN UNSURE OPTION IN THE POLL) I mean gah lol i just dont know how i feel towards it.

lol i wonder if they were actually looking for people to pick up the importance of these reforms being created by one man Lycurgus to the society

thats pretty easy dude lol if u cant get this ur fucked. but anyway its pretty much only difference is supplied energy and resultant energy think about it that way cna u get it now??? if not read the suggested answer in success one book?
