i have sent one not exactly as per iitpattern but you can practice with.i will send u more infuture

please tell me what are the criterias for comparing stability of two chemical compounds? also which is more stable cyclohexane or benzene?why?

study trigonometry by k c sinha.it is best book for trigo on the earth according to me. it is both irodov and h.c.verma as u use it. Publishers of book are STUDENTS FRIENDS PATNA. solve simple problems first and then try to battle the tough ones

moment of inertia of continous mass systems can be calculated by integration.

KEY STEPS-

1.write dm of a small element which is at a distance dx from the axis of rotation.

2.use I = integral of r²dm over the entire length,area or volume respectively as you have chosen linear mass density (

) , surface mass density (

) , volume mass density (

) for writing dm.

3.remember standard formulas for ring disc cone hollow and solid sphere etc. and use it for writing dI and integrate.

please tell me what are the criterias for comparing stability of two chemical compounds? also which is more stable cyclohexane or benzene?why?

please give systematic steps to identify and solve problems based on conservation of momentum

what is a psuedo force?what are different types of it & how it is dealt with newton's laws in mechanics

is earth an inertial reference frame?

FOR WHICH RADICALS INDUCTIVE EFFECT DOMINATES OVER MESOMERIC EFFECT.

when a man sits on chair the weight of man acts on man itself.actually it acts directly to centre of gravity.the magnitude of force is mg and direction is towards the centre of earth.
