this is correct if the volume does not change ...so pressure would increase...

But if you look at question 15 in the same paper both options are given although the ms says that it doesn't expand.

molecules cannont expands....and according to the formula 1/2m(v)2:k.e when temperature increases the energy increases and hence the velocity(speed)of the molecus...as volume does not change the molecules cannot move further apart.........

So you mean that for calculating the time we have to cosider ONE wave ONLY? And one wave means 2 in phase points i.e one crest and one trough successively. Right?
Not necessarily, read the question again. It says one complete rotation of the motor, which will produce one wave

yeah.....but it also dependson question as it may ask the time for more thn one waves......

in b(ii) y cant the ans be blood...the tissue tht is.....does blood contain high amoount of glucose...y o y
1% is way too less. It may cause shock or coma. Blood contains much more glucose. If it has only 1%, then how would it supply the immense amount of glucose in respiring cells

the question states name a tissue which would have much more thn 1%.......

The resultant force in an object moving in a circle would be towards or away from the circle? If its towards i.e centripetal than what is the centrifugal?

blood contains much less glucose than 1 %
actually its 0.09 % something
liver and muscles would have the most conc.

inside the circle that is centripetal
there is no such thing as centrifugal force in pure physics, it is a non-scientific concept
ok then thats weird

how hydrogen carbonate reacts with CO2,what is the equation and why its product is yellow in color?
Is it part of the O Level syllabus?

yes, i think because it is part of bio atp past paper question.

Hydrogen Carbonate, from what I recall, is used in the Bio questions involving respiration/photosynthesis where you have to see if CO2 is being produced or used. Nothing more. You're not supposed to know the equations AFAIK. If it's a particular question that you've seen in a past paper, please link me to it.
