1.	The key feature of Bohr’s theory of spectrum of hydrogen atom is the quantization of angular momentum when an electron is revolving around a proton. We will extend this to a general rotational motion to find quantized rotational energy of a diatomic molecule assuming it to be rigid. The rule to be applied is Bohr’s quantization condition.In a CO molecule, the distance between C (mass = 12 a.m.u.) and O (mass = 16 a.m.u.), where 1 a.m.u. = 5/3 x 10-27 Kg,is close to(a) 2.4 x 10-10 m(b) 1.9 x 10-10 m(c) 1.3 x 10-10 m(d) 4.4 x 10-11 m
Answer» Correct Answer is: (c) 1.3 x 10^-10 m I = (m₁m₂ / m₁ + m₂)r².

How do biofertilisers enrich the fertility of the soil?
Read carefully the passage and select the correct answer out of given four options:Biofertilizers are organisms that enrich nutrient quality of the soil. The important sources of biofertilizers are bacteria, fungi and cyanobacteria. The symbiotic association of Rhizobium with the root nodules of leguminous plants is the common example.
