Water is filled in a uniform container of area of cross section A . A hole of cross section area a (a/A = `10^(-3)` ) is made in the container at a height of `20 m` above the base . Water streams out and hits a small block placed at some distance from container . With what speed ( in cm/sec ) the block be moved such that water stream always hits the block ?

Water is filled in a uniform container of area of cross section A . A hole of cross section area a ( lt lt A) is made in the container at a height of 20 m above the base. Water streams out and hits a small block on surface at some distance from container. Block is moved on surface in such a way that stream always hits the block. The initial velocity of the block (in m//s ) is (Given (a)/(A)=(1)/(20) ). (Take g=10ms^(-2) )

Water rises to a height of 20 mm in a capillary tube having cross sectiona area. If area of cross section of the tube is made A/4 ,then water will rise to a height of

Internal cross sectional area of a pipe is 100cm^(2). How much water can be contained in 10 m length of the pipe.

In a capillary tube having area of cross - section A, water rises to a height h. If cross-sectional area is reduced to (A)/(9) , the rise of water in the capillary tube is

In a capillary tube having area of cross - section A, water rises to a height h. If cross-sectional area is reduced to (A)/(9) , the rise of water in the capillary tube is

Water is filled in a container upto height 3m. A small hole of area 'a' is punched in the wall of the container at a height 52.5 cm from the bottom. The cross sectional area of the container is A. If a//A=0.1 then v^2 is (where v is the velocity of water coming out of the hole)
