wen an object topples it will have only one point of contact before tppling....in questions....we solve it using torque equations...we take moments abt point of contact and equate the torqus

i think adis ans could be a prob it is only applicable to cylinder becoz the real concept behind is

 sice the volume is not A(dx/dt) in case of a sphere(check it out.....)

i think thats rite st line is simple case of relative motion if there is diff in angle of projection,it can vary....

just simplyfy the projectile motion into x and y comps and subtract it from wiewers x and y then u will get an idea of the motions

calculate the change in tension,and apply freq pro to root of tension.and tension will be equal to weight or effective weight

[H]+ = 10 ^-10 plus 10^-7(from water i guess use it in nerst equation u can get i hope...not sure of the metod but tell me if u get...

This Post 0 points    (Olaaa!! Perrrfect answer.   in 0 votes )   [?]

Depends on many things ur determination how far u r in ur syllabus and ur potential ,i mean if u r a dropper then u must be having sum back ground knowledge stress on in importan topics n mathematics like 2d and calculus;physics optics and thermo with electrostatics (arihant s gud) then chem avoid complicated organic just stick with JEE portion and mug inorganic from NCERT and physical forget it u will never finish

any way keep ur hopes up u can get in if u can...........

Try origin shift to A(-2,-3) then line passes throguh origin so y= mx form use origin shift on both line as well ;get the equation simplified in m as use AB.AC =20 get the equation ;shift it back after simplification;

this is not a reply but if u ever found a way can u please tell me also

iam also in +2 ,my FIITJEE AITS results arent tooo gud .....

so if u ever found a sol tell me too

thanking u in advance

This Post 0 points    (Olaaa!! Perrrfect answer.   in 0 votes )   [?]

Do u mean voltage senstitivity??? If it is it cant be increased becoz cR/BAN term R/n term is a constan ie resistance per unit length which is a constant fer a wire..

Not quite like a ring, becoz in usual has hypothetically has no thickness, i suppose its becoz if lenght were comparable with diameter filed otside would not cancle itself i supose check HCV for futher reference..

This Post 0 points    (Olaaa!! Perrrfect answer.   in 0 votes )   [?]

Yes it is based on Gryscoping effects its a phenomenon called processing,that a change in abg momentum creates an change and induces an extra torque its quite complicated,learn it its worth it, Lot of phenomenon like twister wheel ,a wheel rolling ,cycle ride is explained on that phenomenon ,they asked my that on KV PY exam interview good thing that i learned.

Sir i would like to comment on certain problems with ur convertionsthough corrct in many places it is still not best for example in the first paper alkane to R-X chlorination not done due to mixture of compounds (not advised for aliphatic) being formed and convertion wont be that easy.second paper deceasing c atom doesnot decerase becox u get the same product again (CHECK CAREFULLY).athough it was very nice hope sir u could modify these areas and keep posting its great work......
