Resitting 'physics in action' tomorrow (friday).
What examples would anyone use for the section C questions?
I would use, Material = concrete
Sensor = LDR for greenhouse climate control
Image = Ultrasound pregnacy scan
Signalling = E-mail
would anyone else recommend something different?
Material = Rubber composite in tyres
Sensor = Strain Guage for weight measurement
Image = Satelite image system (infrared)
Signalling = E-mail also
hey, im doing the second module for the first time tommorrow as well and am really nervous i have kinda just given up, as have just had an exam this afternoon so only had time to revise this evening and its all so confusing, i was never really taught it properly, i just hope the majority of it is on vectors, cause that's easy, i don't understand phasors and all that at all. Oh well, hops it goes ok tommorrow, it's my Bday tommorrow as well! so it would be a nice suprise if the exam went well
I did both papers 2day (I am in year 12), i didnt think they were 2 bad, what did u think of physics in action?!
physics in action wasn't as easy as i had hoped, but it was ok. i didnt manage to finish the last question though. i wasnt expecting a refractive index question in section C either.
the back page had a graph on it; was it an easy question? because i didnt get that far
how was the other paper?
The last question was pips. 3 or 4 marks on the back page I think.
1 for drawing a line and 2 for a division (it could have been three)
hey r u doing the field particles magnets exc exam next week? what sor of marks do u need for a B out of 70?
its pretty hard that paper
mine was a resit too, now ive got to prepare for a2 on thursday. its gna be a tough one and i'll be happy with a low C. physics seems to be the most difficult subject to revise for - u think u know it all but u just feel helpless in the exam
