Physics Unit 2. How was it ???!!!
what do u expect the grade boundary for an A to be ? -
Physics Unit 2. How was it ???!!!
hahah i know it from unit 3b its right -
Physics Unit 2. How was it ???!!!
hahah no worries 2 marks btw the finding refractive index question i said plot a sin (i) sin (r) graph and find the gradient ...etc i wrote measure angle of incidence and angle of refraction and vary them and find gradient cause mu=sini/sinr -
Physics Unit 2. How was it ???!!!
i skipped MCQ but got back to it later -
Physics Unit 2. How was it ???!!!
hahaha that made me feel better btw the last question the part about using the same power supply i wrote that current is the same in series and the voltage will depends on its resistance therefore the largest resistance ( main lamp) would get a high voltage ..etc and thus it can supply the power... -
Physics Unit 2. How was it ???!!!
the multipel chooice i choosed standing waves is a violin string the energy part i wrote mgh/IVA the drift velocity was v/2 since length had nothing to do with it -
Physics Unit 2. How was it ???!!!
this is not my full answer :P i guess i'll get 2-3 mark -

Physics Unit 2. How was it ???!!!
the part about using ammeter with non-negligable resistance and volt-meter with low resistance i wrote that when voltmeter is connected in parallel the current passing through the load variable resistor will decrease and the current in the circuit will decrease due to decrease in resistance so... -

Physics Unit 2. How was it ???!!!
i choosed polarization because in one of the pastapapers i solved it said that the reflection at oil or something will cause a pattern of color due to super-position ..etc so it had to be included about the filament im not sure about it :P well no worries no one is right till now -
Physics Unit 2. How was it ???!!!
i mean fluorscent lamp same is distingusihable , the round lamps in the pic are filament -
Physics Unit 2. How was it ???!!!
btw last multiple choice i choosed polarization although some said super-position not sure -

Physics Unit 2. How was it ???!!!
i wrote that current decrease hence temperature of filament decrease therefore less vibration of the atoms so less collisions with flowing electrons therefore less resistance some of my friends disagred -
Unit 2 Physics notes!!
is line spectrum the absorption or emission spectrum? -

Mechanics!
C2 january 2013 was a piece of cake yet it was 64 :P i did many stupid mistakes in this session exam lets just hope its 61-64 -
