I have my exams in 12 days.. Please help me to complete chemistry... By telling some important concepts only...
students must cover all the syllabus to score good marks in exam Since questions in exam are asked from all the topics but still the most important topics areAtomic StructureGaseous & Liquid StateElectrochemistryChemical KineticsNuclear & Surface ChemistryChemical Bondingd-Block ElementsCo-ordination CompoundAlkyl HalidesAromatic CompoundsThermodynamicsp-Block ElementsGeneral Organic ChemistryIsomerismAldehydes and KetonesCarboxylic Acids & Its Derivativesif you dont know the concepts in organic chemistry atleast try to memmorise organic name reactions

Dear Student,Please find below the solution to your problem.If the guard at the rear of B is passing the driver at the front of A then B has not only caught up the initial distance between the two trains but has also completely overtaken train A.Let the original separation distance be x. Then distance to be covered starting with relative velocity zero is s = 800 + x (800m being the overtaking distance from front meets rear to rear leaves front).Distance s covered at acceleration a starting from (relative) speed zero = 1/2 at^2 which for t=50 gives:= 0.5 x 50^2 = 1250mSo 800 + x = 1250 Therefore x = 1250 -800 = 450m.Thanks and Regards
