We have a normal tendency to read a question and get a go for it. Instead read the question twice, make a box and write down all the important parameters mentioned. I am sure this will help.

  LHL is in the form 2(-infinity) which tends to 0 RHL is in the form 2^(infinity) which tends to infinity Hence the limit doesn't exist

The material mentioned is more than enough for a sound preparation. But I would recommend you to buy books consisting of model papers and give them in regular intervals in stipulated time.

2^0 will come in RHS of minus sign 10 times. Its contribution -(10)(2^0) 2^1 will come in RHS & LHS of minus sign 9 times & 1 time respectively. Contribution -(8)(2^1) Similarly contribution of 2^2 is -(6)(2^2) and so on.... M = -(10)(2^0)-(8)(2^1)......+8(2^9)+10(2^10) = 10(2^10 - 2^0) + 8(2^9 - 2^1) + 6(2^8 - 2^2) + 4(2^7 - 2^3) + 2(2^6 - 2^4) = 10230 + 4080 + 1512 + 480 + 96 = 16398 Sum of digits of M is 1+6+3+9+8 = 27

No skipping my friend. Question can come from anywhere. Doing NCERT is enough which I think is not a big job. Salt analysis is important in my opinion as its not big and questions do come.

Sodium and potassium compounds are soluble in water. The main species in water are the aquo complexes.

Oxygen is supplied either from pressurized tanks, an oxygen generator (which can form oxygen from the electrolysis of water) or some sort of "oxygen canister" that releases oxygen by a very hot chemical reaction.

This test is employed to detect the presence of nitrogen, sulphur, halogens, and phosphorous in an organic compound. These elements are present in the covalent form in an organic compound. These are converted into the ionic form by fusing the compound with sodium metal.

Put x=w (cube root of unity) and compare the real parts. You'll find the answer as 1.

If the surface is very sticky or rough, a 2 N normal force might require you to push the object with 5 N. The coefficient of friction would be 2.5, showing that the value can be greater than 1. Also, if some special glue was used to attach the object to the surface, such that you could not move it no matter how hard you pushed, the coefficient would be infinity.

x=0 is not in domain.For x>0 log|x| = logx whose differentiation is 1/xFor x<0 log|x| = log(-x) whose differentiation is again i/zso d(log|x|)/dx = 1/x

It depends on your convenience. If the projectile is thrown in a simple plane then take horizontal & vertical axes as x-axis & y-axis respectively. If it is thrown along a wedge take the inclined plane as x-axis and perpendicular to the incline as y-axis and accordingly assign components of g.

Covalency is the sharing of a pair of electrons by two different atoms of same or different elements. Each element contributes unpaired electron ( a valance electron) to form the bond.

Its good but not enough. JEE requires handful amount of practice and you need to do other books too like Arihant or TMH.

Since it moves with steady speed its kinetic energy remains constant. Work done is the change in potential energy caused by change in height. W = mgh = (20000N) x (120m) = 2400000 J = 2400 kJ

As it involves lots of numericals parctice is must. Start with NCERT. Do a lot of paperwork initially and then when you find yourself in comfortable zone write less and think more. Afterwards practice from P Bahadur. Don't indulge yourself in different topics at a time. Pick one topic, finish it off and move on.
