Question 1

According to laws of magnetism 1) law states that each magnet consists of two poles namely north(N) and south(S) 2) law states that like poles repel each other and unlike attract each other3) law states that when a bar magnet is cut into two, two magnets are attained

But, suppose we have bar magnet, 1st side is north and 2nd side is south, when the bar magnet is cut into two. According to the law two magnets should be obtained but when you do this as 1st side was north so according to law the opposite side to this should be south and 2nd side of the bar magnet was south so the opposite side should be north and when u try to join the Two magnets again into same shape as they were the won't but why ?

They repel each other. According to 2nd law only and only like pole repel each other. So the end points from where had cut the magnet they are either are N=N or S=S. Then according to 1st law a magnet consists on only two and unlike poles in a single magnetso this makes this laws contradictory proving that they are all wrong++++++++++++++++++++

The centre of the magnet is at the neutral zone of the magnet. theoretically, there is no polarity at the centre. but, when at the centre it is borken/bisected each of the broken ends will assume polarity opposite to the that at the rear end. it means, one of the broken ends will have ''N'' and another one will have ''S''. So each of both pieces of the magnet will become a complete magnet. This is according to the 'Molecular theory of Magnetism''. so the broken ends will attract each other ( not REPEL as commented above ) because unlike poles attract. So, nothing contradictory is seen. one can better understand if Molecular theory of magnetism ' is read out in its simpler version.

Question 3

In a longitudinal wave the particle displacement is parallel to the direction of wave propagation. The animation below shows a one-dimensional longitudinal plane wave propagating down a tube. The particles do not move down the tube with ...
