Can anyone post notes on transistors capacitors astable bistable circuits ? (according to the syllabus )
Thanks in advance

ya! i need it too!Can anyone post notes on transistors capacitors astable bistable circuits ? (according to the syllabus )
Thanks in advance
optional? they are in syllabus! however, they stated the topic is only in the alternative question but it doesnt mean we do not need to study!!! if they make both question the same topic in the section then how?They're optional
I never touched them.
answer is (iii)? because slow cooling will produce large crystal?
isnt like that? i tot all blood vessel will contain urea? just some with different concentration?can anyone explain me the route taken by the urea before excretion.. Renal artery contains urea, and renal artery is like a sub-artery of aorta, so does aorta contain urea?! Urea comes from liver, and the hepatic vein goes to the heart.. it contains urea, so is it like that urea goes all the way through heart to aorta and then to renal artery? This would mean all arteries are going to contain some amount of urea in them! This route might not be possible then.. HELP.
iii
The water in iii will evaporate slowly, this will allow zinc sulphate in the solution to saturate and the particles will likely clump together to form big crystals by the time the water has evaporated.
I guess the route i posted was correct! Because in dialysis we draw the blood from artery, and not vein.isnt like that? i tot all blood vessel will contain urea? just some with different concentration?
23) It's just a dye that loses its colour due to CO2 ( see the question, it says the dye loses its colour in tissues actively respiring)http://www.xtremepapers.com/papers/CIE/Cambridge International O Level/Biology (5090)/5090_s10_qp_12.pdf
explain
Q. 23 and what is the blue dye they are referring to?
Q. 26 why c is not correct?
Q. 28
I said 'almost' the same, so if x=o, the total would 405, that's the nearest to 430. other options will give greater differencesi dont think your logic for Q28 is correct
btw that is what i thought but that is incorrect
the total number of seeds are not same
that is the total no. of seedlings kept in dark are 320+110=430
and in 405+x that are kept in the dark
is light one of the condition for seed to germinate?I said 'almost' the same, so if x=o, the total would 405, that's the nearest to 430. other options will give greater differences
thank for?thnak you people !!
answering my question !thank for?
