physics 22
the wave was progressive and transverse as (according to the diagram) it hadnt reached the other end yet meaning that there was no reflected wave. A stationary wave is formed when the reflected and incident wave superimpose. -
how was physics p22?
in 1 complete oscillation a moved from lowest to highest then back to lowest point which us equal to 4amplitude. Therefore the amplitude is 20mm. the wave was progressive aa it hadnt reached the other end . A stationary wave is formed when the reflected and incident wave superimpose. -

i personally found the paper easy. though i made a silly mistake which will cost me 3 marks. -

physics help( cie exam)
suppose u get an answer say 1.3666666666A for part (i) and give the answer to 3sf 1.37A. u need this answer to calculate another quantity say voltage for part (ii). which value should u use to calculate the latter 1.37A or 1.36666666666A? -

sorry about that yep no restriction - together -
How was maths p62?
7 (i) 3(1/6) = 0.5 (ii) 9- 1/30 10-3/10 11- 0.5 12- 1/6 ( sum = 1) (iii) not independent P(R) x P(S) = 1/5 which is not euqal to P(SnR) = 1/6 (iV) not mutually exclusive P(SnR) = 1/6 ( not 0) -

How Was Your Physics 33 Practical ?
what masses did u use? at my centre, we used 1. 100 g mass hanger 2. 100g slot + 100g mass hanger and also the distance between the two retort stands ( rubber band length) was appoxmiately 15cm -

How Was Your Physics 33 Practical ?
my gradient 1.10 and y- intercept 1.12 resistivity 7x10^-7 question 2 - relationship not valid -
physics 33 100% true guess here.
the apparatus u predicted was right(rubber , weight , stopwatch, electrical components). Now about the experiment, u did mention that it was SIMILAR to 2011 p34 may/june which it was in fact. the only thing that didnt match your prediction was that we had to use a balance(mass) instead of the...
