PLZ NOTE: DUE TO THE RING ACTIVATION BY + R GRP. -OH, THE META POSITION HAS LOW ELECTRON DENSITY. THUS, META DERIVATIVE IS A RARE CASE OR NEEDS EXTERNAL AGENTS.


P-NITROPHENOL, DUE TO NITRO GRP.'S ELECTRON WITHDRAWING NATURE, HELPS DECREASE DENSITY AT O, MAKE A STABLE PHENOXIDE ION. THE STABILITY IS LOWER FOR META DERIVATIVE DUE TO RING POSITION. THUS ORDER IS

A-DNA is 2.5 nm in pitch of the helix. B-DNA is the biological DNA which is the genetic storage for the human body. C is for complimentary and Z is synthetic. hence, should be B-DNA

nope. wherever the barren land is will be cut accordingly. keeping in mind that the barren part may not b in a corner or near the center, the cut position will change.

this is a gr8 thread. to learn space quantisation read 'three roads to quantum gravity' by Lee Smolin. tohugh it is a very novel topic, in terms of hybridisation, with interference of the wave functions forming anti-bonding and bonding orbits, its quantisation is represented in terms of n,l,m and s quantum numbers. obeying pauli's exclusion the hybrids can be expressed in terms of orientation, shape, principle and spin only angular momentum and magnetic moment of electrons.

3) to be divisible by ten, permute the number of divisors of 180. 1,2,3,4,5,6,9,10,12,15,18,30,36,45,90,180. which is 18.

well written. actually the euler-fermat function is a generalization of the FLT.

put x=tany


the sum is then


integral from -1/root3 to 1/root3 of (tany)^4/1-(tany)^4x 2tan^-1x x d/dx of tan^-1x. as the function is odd the integral is

for even f(x)=f(-x)


for odd f(x)=-f(-x)


 


this is neither, hence, neither odd nor even.

using moment of inertia and the gravitational entropy the estimated height of the tallest mountain is about 22 km.


using thermal physics one can say tht rotational inertia alongwith mass would increase angular speed in a smaller orbit, thus probably the core would be denser and hooter. this tectonic movement cna only reach a particular level before causing calamities, hence, the height to balance 2/5 MR^2 can b found

due to the apparent covalent nature of the house, the rajya sabha will b dissolved in benzene, CCl4 orCS2.


 


p.s. this depends on the availability in the chem. lab.

56.


here's how.


a minimum of a ball per box. let box B and C have 1 ball each. then box A has 28. keep on decreasing a ball from box A and figure the combinations in boxes B and C. the total is 1+1+2+2+3+3+4+4+5+5+6+6+7+7.

@ sahilgupta. isnt it symmetric 2 use an irrelevant method for an irrelevant question? nehow, the only 'way' to solve these is by bringing in the indeterminate form of 0/0 or jss by dividing by 0.

the point is tht the 2 dollars 2 as tip are included in the 27. hence, it is 27(paid) + 3 (received) tht is the total.

tht is more or less da ans. da sensitivity and resolution of da camera is a mechanical property and can detect em radiation of different wavelengths. the eye can 'perceive' in terms of optical pulses but the body can in terms of heat. so 'seeing' IF signals via a captured image or capturing da image is perfectly coherent wid no exceptions.
