  4) C

  5) D

  6) D

  7) B

  8) not too sure but i wrote A ( might be C)

  9) D

  10) B (sound is the ONLY longitidinal wave)

  11) D

  12) A

  13) D ( big waste of paper on this one)

  14) D

  15) B ( total voltage of cell = 0.6X10=6V , 6V/30ohms = 0.2)

  16) B

  17) B

  18) C ( i wrote A during my exams due to error while calculating T.T)

  19) D ( C is neutral point , B is going downwards, remember tht the poles are SOUTH)

  20) A

  21) D ( not too sure, many of my friends wrote C)

  22) D ( came out word for word in TYS)

  23) D ( hentam)

  24) D ( again, came out word for word)

  25) B

  26) A

  27) A ( D is combustion- exothermic , B and C is bond breaking which is endo)

  28) D

  29) C ( could be B )

  30) A ( CO2 is acidic therefore pH < 7)

  31) C ( only viable answer)

  32) D ( both in group 5)

  33) A ( i dun know why poeple wrote potassium )

  34) A

  35)D

  My sentiments exactly.

  omg u are rite o,o. i just realised tht the magnetic field for this are for NORTH poles            ( doh!!!!!) il make the necessary changes

  That's good to hear. So how much did you get for this paper?

   

• shredyellow

  12 Nov 08, 15:40

  Arabian dude your very first phy answer is already wrong haha. its C . i thought it was A too but when i checked after i finish the paper i wanted to change to C but the person was asking for the paper already. fuck.

• Arabiandude

  12 Nov 08, 19:01

  Wha? how come its C. the vernier caliper's second bar stopped at the 2.20 marking amirite? then on the second bar itself it touches the 0.03 marking. the only way i think it could be C was if the reading on the second bar was 0.3 not 0.03. im not entirely sure though.

  can u tell me ur reasons for choosing C instead of A?

  You're supposed to read where 0 on the vernier calipers passes the scale, not the edge of the vernier calipers. Duh.

  People chose potassium (for question 33) because the reactivity series as we were taught begins with potassium as the most reactive, hence leading them to think it's the most reactive out of those 4. They probably didn't check the periodic table and remembered that reactivity increases downwards in Group I. You made mistakes yourself, you shouldn't be acting like a smartass here.

  EDIT: Oh and in case you were wondering, I chose caesium as my answer.
