1.	The V-I graph is given for two conductors of same area and length. If `sigma_(1)and sigma_(2)` are the cnductivities of the conductors 1 and 2 respectively, `(sigma_(1))/(sigma_(2))=` A. `2:1`B. `3:1`C. `1:sqrt2`D. `1:3`
Answer» Correct Answer - D `sigmaprop1/R"When l and A=same"` `Rprop tan theta,sigmaprop(1)/(tan theta)` `(sigma_(1))/(sigma_(2))=(tan30^(@))/(tan60^(@))=1/3`

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.
