I just don't understand like..anything in P456 especially P5 omg
P4 can be nice if there's loads of graphs. P5 makes no sense. P6 is lovely when they ask you questions from the spec Not questions on patients and X rays and what radioactive element to use.

P4 - I have a deep dislike for graphs in exams P5 - I definitely agree on that point. P6 - I don't even know half the content at the moment..like half lives etc
Dude that really isn't as bad as it looks! Just do some practice questions absconded you got it you'll be begging for it to come up! My teacher made me a pro at that chizz
I just don't understand like..anything in P456 especially P5 omg
2 years of experience under my belt
Mmhhmm p6 is not to bad because it feels like chemistry again and 04 is just equations so just do the workbook for that! But p5, I hate that ****! But to make sure I'm not learning it morning of, I'm doing a long night to complete it tonight haven't even started-_-
I'm making comprehensive questions for each page in P5, anyone interested in spoiler answers just say What happens when I rub a polyethylene rod and a cloth duster?what is the force causing this? True or false: protons being scraped off and onto another substance gives the other substance a charge? When I remove and donate electrons I turn the prior materialsc atoms into ___? Explain static electricity with reference to two insulating materials being rubbed? What are the rules of attraction and repulsion? Give 3 examples of static electricity build up? Cgp book page 1 for p5
Pg 2 What is current? Why do metal conductors carry charge?why not in an insulator? What's a complete circuit? What condition is their for current to flow through a component? What is voltage?units? How does resistance occur?units? Explain the relationship between resistance,voltage and current. What's power? How does a battery do work on a circuit? A xbox rated at 230v, 2KW. find the current it draws.
pg 5 what is meant by a series circuit? give 5 rules, 3 about V, I and R and 2 about the cell and current, regarding series circuits? explain a parralel circuit? why is this prefer in places llike houses? explain how current is shared and how it varies in a parralel circuit? rule of voltage in a parralel ciruits?
pg 6 how is mains electricity produced and at what voltage?what type of current (DC or AC ) is it and why? explain magnwetic induction? how is AC current produced? recall 4 factors that affect the size of the voltage induced? pg7 explain what transformers do, why they are used, how they work and why they only work with AC? a transformer has 80 turns on the primary coil and 1600 on the secondary coil. if the input cvoltage is 1000v what is the output voltage? pg 8 describe a magnetic field?relate this to a current carrying wire? how about a rectangular coil? http://www.s-cool.co.uk/assets/test_its/alevel/physics/forces-in-magnetic-fields/dia02.jpgb - explain how can i find the resultant force of the above picture and hence the motion the wire is forced to?find it for the wire above even though it basically shos you ? pg 9 filll in the blanks if a rectangular coil of wire carrying current is placed in a ____ magneitc field, the force will cause it to____. what rule can you use to work out which way it'll turn? how are wheels turned? ( make references to the motor effect, 6 marks) list 4 examples of the motor effect in action?
It's not you it's me... A- I don't think it could be part of the similar category as I think the similarities had to be seeable and pH Isn't visible; you need to test pH. So I said diff as they will likely have diff pH on a pH meter which is really accurate- this point believe is wrong because why the shell can't they have the same pH? B- I'm if the question said stuff about dilute or dissolved I believe this could be a valid similarity as hydrogen bibles will be produced (I only said hydrogen gas and that's cloudless so once again my justification is whack) C- only answer I'm certain about and it is a similarity as it produces a white precipitate on both reactions- correct me if I'm wrong D- when I looked up the reaction on the front page I didn't see chloride ion s to produce any precipitate this way so I don't understand people's justification of this being a similarity but I'm sure someone could tell me...(ps. I said it was a difference because f this as one would react to produce a precipitate and one wouldn't-something along them lines)
What did you put? If someone can justify D as similar then I'm thinking that's the answer: CD AB
C does not produce a white precipitate on both. This is because c was barium chloride which only detects sulfates and there are no sulfate ions in hydrochloric acid.

I might spend a long night doing it too, don't have to get up til 10am
Depends if I have motivation though, 'cause there's a lack of that in me these days
