Crystal Field Splitting Energy: Crystal field theory was given to explain the structure and stability of the coordination complexes. This theory has some assumption like the metal ion is considered to be a point positive charge and the ligands are negative charge. The complexes are formed mainly by the d- block elements due to their variable oxidation states and variable coordination number. The d- subshell has 5 degenerate orbitals. when the ligand approach to the metal ion, the energy of the degenerate orbitals is increased and further splitting of degenerate orbital takes place into t2g an

Let A(-1, 1),  B(0, 5), C(3, 2) be the vertices of the given triangle.The equation of AB is         or   y = 4x + 5                       ...(1)     The equation of BC is        or                      ...(2)     The equation of CA is               or            Required area = Area of ∆ ABC= Area of region AMOB + area of region BONC - area of region AMNC

Avogadros number NA = 6.02 x 1023  = 1 mole∴ 6.02 x 1020 molecules = 0.001 mole in 100 mL (0.1 L solution)∴ Molar concentration  = mol/volume in L =0.001/0.1 = 0.01 M

Answer -: (CH3);,CHOH...............‘The oxidation product of X reacts with phenyl hydrazine, thus it contains >C=0 group. The same product does not (give) silver mirror test. Thus, it s a ketone, because only aldehydes give silver mirror test.
‘Thus, the compound X must be 2° alcohol, as only secondary alcohols give ketones on oxidation and hence, X is (CH3),CHOH

By the time TISCO was set up the situation waschanging. When in 1914 the war broke out, steel produced in Britain now had to meet the demands of war in Europe. So imports of British steel into India declined and the Indian Railways turned to TISCO for supply of rails. As the war dragged on for several years, TISCO had to produce shells and carriage wheels for the war. By 1919 the colonial government was buying 90% of the steel manufactured by TISCO. Over time TISCO became the biggest steel industry within the British empire.

The role of credit for development:(i)Credit is available normally from two sources. These can be either formal sources or informal sources.
(ii)Terms of credit vary substantially between formal and informal lenders. At present, it is the richer households who receive credit from formal sources whereas the poor have to depend on the informal sources. It is essential in modern economy to make terms of credit flexible with formal sources of credit e.g. Banks etc. in order to safeguard interests of the poor sections of society in India.
(iii) In prevailing situations, if credit can be made ava

Let A be the point of observation, C and E be the two points of the plane. It is given that after 15 seconds angle of elevation changes from 60° to 30°.i.e., ∠BAC = 60° and ∠DAE = 30°. It is also given that height of the jet plane is 1500 [Since jet plane is flying at constant height, therefore, CB = ED = In right triangle ABC, we haveIn right triangle ADE, we have
Putting the value of (i) in (ii), we get1500 + BD = 4500⇒    BD = 3000∵ Distance travelled in 15 sec=  CE = BD = 3000 metres,Now, speed of plane (m/s)     =    and speed of plane (km/h)     =                                      

Human geography attempts to explain the relationship between all elements of human life and the space they occur over. In this way human geography assumes a highly interdisciplinary nature. It develops close interface with other sister disciplines in social sciences in order to understand and explain human elements on the surface of the earth.
