1.	A block is hanging at one end of the massless rope passing over a fixed smooth pulley. From other end of the rope a man of same mass climbs with an acceleration "x" relative to the acceleration of rope which is a. The value of "x" is :
Answer» Magnitude of acceleration of string equals acceleration of block. For man, T−Mg=Ma_man For block, T−Mg=Ma ∴a=a_man. String accelerates downwards with a, and man acclerates upwards with a. Hence relative acceleration x=2a

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.
