1.	If a particle starts moving along a straight ine withinitial velocity u under contact acceleration a, its displacement with time is given by the relation `x=ut+(1)/(2)at^2` Q. Differentiation of `x` w.r.t. `t` will beA. `u+("at")/(2)`B. `u+"at"`C. `u+2"at"`D. `(ut^(2))/(2)+(at^(3))/(6)`
Answer» Correct Answer - B `S=ut+(1)/(2)at^(2)` `v=(dS)/(dt)=u+(1)/(2)axx2t=u+at`

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.
