C4 today...Summer 2013
it a typo error haha but glad to hear that u got the same answer :) -
C4 today...Summer 2013
I got for 7b.(-3,6) because its parallal to the y-xis if it was parallal to x-xis then you would get (-6,3) which is wrong. I got for the range question 0<f(x)<2 , for 8a. P=1 , question was amazing, u had to bring the (1-x)^-0.5 and expand normally using the binomial formula and then multiply... -
c3 june 2013
i got an A c1 A in c2 , B S1, c3 c(in Jan) m1 waiting, c4 doing it on the 18th june :) whos ready???? i like c4 more than c3, c3 today made me hate maths :( the last question was some M1/physics question, so trickkkky -

Physics Unit 2. How was it ???!!!
the best question was the 5 mark graph question who agrees?? -
Physics Unit 2. How was it ???!!!
the current for both lamps was different and in a series circuit the current is the same, one was 0.17A and the other lamp was 0.2A so i think the circuit is in parallal, well thats what i did :) -
Physics Unit 2. How was it ???!!!
my ans was a pure guess, i was referring to the gold leaf experiment where you shine uv light on the surface -

Physics Unit 2. How was it ???!!!
, hopefully we are right, i think the grade boundries are going to 57/59 for an A, unless people did bad on the electricity questions -
Physics Unit 2. How was it ???!!!
did anyone use E=hf for working out the frequency, i multiplied the work function by 1.6*10-19 and divided by planks constant, who else used my method :) and i said its ultraviolet range -
Physics Unit 2. How was it ???!!!
i mentioned vibration of the lattice is less because temperature decreases as current decreases therefore less collisions between the atoms -
Physics Unit 2. How was it ???!!!
hi guys, there was a 5 mark question on a graph, i got a gradient to be -r a negative gradient , i dont know if im right?? and Q1 i put the opera singer, because echos are standing waves. why is the circuit series i put parallal? the current are both differnt for both lamps???
