    HOW WAS PHY P33?????

    your values are very much near to mine so i hope they are correct..and for k i think we cud use cm/s and mm together as long as we used same units while calculating both values..

    HOW WAS PHY P33?????

    not in this case...bcuz human reaction is involved

    HOW WAS PHY P33?????

    it had to be converted..our examiner specifically told us not to forget to convert it...nice guy :p

    HOW WAS PHY P33?????

    and my gradient was 1.25 and y intercept was -.0175

    HOW WAS PHY P33?????

    haha yeah faheem is right to find percentage uncertainty..take two readings..take their average..and find the difference between one of the readings and the average reading...difference/average reading x 100..this is the best method..other methods are also correct..we had to see human reaction...

    Physics Practical/P33 Details and General Practical Tips

    can anyone here tell me the difference between and functions of a semiconductor diode and a light emitting diode? and are there any pointers for while setting up the circuit,,any thing we should be careful of?

    Physics p33 errors

    hey..could anyone tell me..which ball..the larger one or the smaller one will reach terminal velocity first and which will have a larger terminal velocity??

    HOW WAS CHEMISTY PRACTICAL?

    judging from the answers that i have heard so far..a lot of people messed up so you should be safe on percentile

    How was chem 33...:D And my Guesses:D..

    umm..did u check the solutions for solubility of white ppt cuz by adding acid in fa3 my white ppt dissolved so technically there should be no sulphate?
  10. A

    HOW WAS CHEMISTY PRACTICAL?

    so it cud be higher right or is everyone else getting a lower value?

    HOW WAS CHEMISTY PRACTICAL?

    hey did anyone get a molar enthalpy change greater than 15.2 in p33
  12. A

    chemi practical how was it ppl ?!

    my molar enthalpy value was 16..i think it had to be lower than 15.2..can someone confirm this?..and could an error be heat loss to the atmosphere
  13. A

    How was chem 33...:D And my Guesses:D..

    hey..cud u tell me the anions for each of fa2,3 and 4 and how many marks could i lose if i had a molar enthalpy change of 16 in my calculations..
