A small block of wood, of specific gravity 0.4 is submerged in water at a depth of 2.9 m. If the block is released from rest. Then choose the correct alternative(s).

A small block of wood of relative density 0.5 is submerged in water at a depth of 5 m When the block is released it starts moving upwards, the acceleration of the block is (g=10ms^(-2) )

A small block of wood of density 0.4xx10^(3)kg//m^(3) is submerged in water at a depth of 2.9m . Find (a) the acceletation of the block towards the surface when the block is released and (b) the time for the block to reach the surface, Ignore viscosity.

A small block of wood of density 0.4xx10^(3)kg//m^(3) is submerged in water at a depth of 2.9m . Find (a) the acceletation of the block towards the surface when the block is released and (b) the time for the block to reach the surface, Ignore viscosity.

A small block of wood of specific gravity 0.5 is subnerged at a depth of 1.2 m in a vessel filled with water. The vessel is accelerated upwards with an acceleration a_(0) = (g)/(2) . Time taken by the block to reach the surface, if it is released with zero initial velocity is (g = 10 m//s^(2))

A small block of wood of relative density 0.5 is submerged in water. When the block is released, it stats moving upwards, the acceleration of the block is (g=10 ms^(-2))

A small block of wood of relative density 0.5 is submerged in water. When the block is released, it stats moving upwards, the acceleration of the block is (g=10 ms^(-2))

A block of material of specific gravity 0.4 is held submerged at a depth of 1m in a vessel filled with water. The vessel is accelerated upwards with acceleration of a_(o) = g//5 . If the block is released at t = 0, neglecting viscous effects, it will reach the water surface at t equal to (g = 10 m/s^(2)) :
