Physics 41...How'd it go?
all same xcept resistance was really confused in that part!!! and yes the speed was around 5000 and the graph of Ek was like d.c bumps right with max Ek when displacement zero!! and about the assumptions due to volume for ideal gases what did u write??? -
Physics 41...How'd it go?
i think we calculated Q in the previous part i think we had to calculate dQ by using dV which we calculated in yet the previous part!! i dont xactly remember i got the value of I so im happy :) -
Physics 41...How'd it go?
the ans for current was given if u got it ur right no matter how u did it ( if u used correct reasoning) btw to calculate current i used Q=It so i didnt need voltage !!! -
Physics 41...How'd it go?
I = Q/t Q we calculated and t= 7x10^-3 because the current only flows while the capacitor is discharging!! -
Physics 41...How'd it go?
and for the r.m.s speed when we consider the temp do we have to consider in K or ^oC my rms speed was coming i think 580 or something!! -
Physics 41...How'd it go?
yeah i wrote since we had to consider three dimensions of motion we have to divide by 3 overall the paper was tough but alhamdulilah went well!! -
Physics 41...How'd it go?
Why 4 i did it with 4 then since we were using average current i redid it with average voltage V=4+2.4 /2 = 3.2!! ahh well hope ill get a mark!! -
Physics 41...How'd it go?
And how were we supposed to derive the equation for ideal gases :/ i just took the average of square speeds and divided by 3!! -
Physics 41...How'd it go?
Guys to calculate the resistance what did u use for V -

Biology MCQ thread..!!
hey ppl can u pls help me with these thanks in advance O/N 04 q38 how do we get D A square metre of grassland receives about 1 047 000 kJ of solar light energy each year. The table shows what happens to this energy. used in evaporation of water 523 500 kJ transmitted to the ground 335 000 kJ... -

too bad dont worry i might come to saudia arabia someday then we can MEET -
Physics practical tips
i still dont understand the uncertainty part its least count/actual value x100 so a micrometer the least count is 0.001 cm so %uncertainty 0.001/our value x 100 right -

take a dictionary and check the spelling of pieces meet me in person then well see whos left in PIECES!!! -
INFO on Phy Prctical 31?
then BookGeekCoolboyz i suggest u get of this forum and stop wasting ur time with these educational talks since u dont even care that u pass or fail in ur xam y dont u leave those who do care in peace!!! -

cylinders hmm thats too vague to revise experiments on altho i heard about pulleys ??? -
INFO on Phy Prctical 31?
yeah i guess rheostat is pretty much confirmed but can it be in the question with improvement cos i cant think the past papers can help if that is the case -
Physics P33 Practical Final Views
how can u have both mechanics questions one question must be for mechanics and the other must be from electricity!!!
