    Physics practical grams or kg?

    lol, agreed ;)

    Is A above 80 or 90 in as level???

    A is above 80 but exactly at which mark that 'A' lies, THAT varies according to grade threshold :)

    Physics practical grams or kg?

    sorry but i still don't think that logically possible really....

    Physics paper 33 messed up real bad

    well, first of all, a value of gradient is NOT fixed so stop worrying....in phy practicals u mainly get marks for small details, like the number of significant figures used, graph plotted,line of best fit and mostly, the WAY u solved the paper. In mark schemes as well u'll notice that they...

    Physics practical grams or kg?

    p was equal to the gradient you calculated while q was equal to ur value of y-intercept and btw ppl, anyone who calculated the y-intercept from the equation of y=mx + c, then its really not possible for ur gradients to be positive since a positive gradient would give a negative y-intercept and...

    Physics practical grams or kg?

    then don't worry beacuse even here at xtreme papers u'll note that most ppl got a negative gradient :D

    Physics practical grams or kg?

    the height was decreasing with increasing weight :O

    nice profile pic,lol

    nice profile pic,lol

    Physics practical grams or kg?

    yes, thats the kind of results i got too

    Physics practical grams or kg?

    yes, totally!

    Physics practical grams or kg?

    it DOES NOT matter whether u use kg or grams.....its good if u use SI units but not at all compulsory. btw, i used mm and gram for question 1

    Physics practical grams or kg?

    mine was negative too and i consulted with many of my classmates....most had a negative gradient ;)

    PHYSICS 9702 P3 help!!!

    look PEOPLE, u subtract the two k values, divide with the SMALLER value of k preferentially.....multiply the answer with 100. Now compare this uncertainty with the %uncertainty calculated earlier....if this value is less than or equal to the earlier value then the relation holds true. Otherwise...

    physics paper 33

    actually thats incorrect, subtract the 2 k values but divide the answer with the SMALLER value so that ur error value can be maximum. the multiply with 100. Now if this answer is almost equal to or less than the uncertainty u calculated earlier, then the relation holds true. If its much greater...

    physics paper 33

    fractional uncertainty= least count/reading uncertainty= least count multiplied by 2 or 3

    physics paper 33

    there will be heat losses to environment, or error in reading the thermometer but DONT write parallax error for improvements u can write the use of data loggers, insulation such as matting, take more than 2 readings and plot graph, dont touch the bottom of the thermometer to the base of...

    AS physics p33

    no, that would make it an electricity practical :P we'll prolly have to measure the rise or fall of temp with the help of a thermometer
  18. oldfashionedgirl

    Improvements Physics Practical

    its not important AT ALL for improvements and limitations to match or concide...... the heating question is actually quiet new,theres never been a question like it before.....we'll have to measure either the rise or fall of temperature with a thermometer :)

    Improvements Physics Practical

    its a force extension pract maybe....theres gonna be stuff like springs and weights
  20. oldfashionedgirl

    Improvements Physics Practical

    in p34, theres gonna be an electricity practical....prolly a potentiometer....and its gonna be relatively easy as far as i've heard :)
