1.	Two block of same mass m undergo headon collision as shown. E is the coefficient of restitution. Choose the correct statement(s) : A. If e = 1, just after collision KE of right block is `(1)/(2)mv^(2)`.B. If e = 0, loss in KE is `(1)/(2)((mv^(2))/(2))`.C. If e = `(1)/(2)`, loss in KE = `(3)/(16)mv^(2)`.D. No impulsive force acts on left block during collision.
Answer» Correct Answer - A::B::D With respect to box, psudo force = mg act upwards. So `F_("net")=0`

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.
