As Simon said you are using p for two different things. You can use the fact that p(1-p) (where 0<p<1) has a maximum value(find it). You can use it to get a bound for your answer.
Write the newton's laws in the frame of the ground. It is an inertial frame. Write down all the forces(along both axes). Also observe that for every meter the car moves, block A moves by 2 meter.
That is not going to work.What you say is maximum is true only for a=b,if you apply AM GM inequality on a,b.Doing so for 1st 2 expressions give x=140,y=260.
*I don't know the answer*
no you dont have to include no.of moles of solid.
no, it would go backwards,as Qp>Kp.
for (iii) and (iv) read le chatelier's principle.

to prove square root function to be bijective you need to specify the domain and codomain of the function.
if codomain is set of real numbers, then its not bijective.
the integrated rate law for 0th,1st,2nd order might help for problem 13.
for q.14 use first two data to find the rate law and rate constant.
then using arrhenious equation and the third data find rate constant at 650K.
use the integrated form of rate law to find the required time.
there will also be the contribution of induced charges on the conductor surface (the net induced charge being zero) on the potential and field inside it.
the field inside a conductor is independent of the charges outside it.if you bring another charge outside ,although the distribution of...
http://en.wikipedia.org/wiki/Thermal_conductionFor the formation of layer of thickness dh calculate how much heat will be transferred from pond to surounding .then use 1D heat conduction formula to relate it to the given parameters.
what is the dependence of period on amplitude?
can you detect the deviation from small angle time period at larger amplitudes(angle) using the instruments you have?
suppose bob is filled with water and there is a hole at bottom how does period change as time progresses?
if the charge q is imagined to be uniformly spread over the plane passing through that charge and parallel to the plates , the charges induced on plates remains unchanged, only their distribution changes.
can anyone explain that.......
for this problem use the fact that two facing surfaces have equal and opposite charges(a consequence of gauss's theorem).when the switch is closed first assume certain charge distribution on each face and use the above fact.you also have net charge on plate2=2Q,
and the sum of charges on plate1...
