A test tube weighing 10g and external dismeter 2.5cm is floated vertically in water by placing 20g of mercury at its bottom. The tube is depressed in water a little and then released. Find the time of oscillation. Take `g=10ms^(-2)`.

A thin vertical tube of weight 12 g and external diameter 1 cm is made to float vertically in water by placing 12 g of mercury at its bottom. If the tube is depressed slightly and then released, determine the time period of S.H.M. Take g = 10 m//s^(2)

A test tube of weight 5.6 g and external diameter 2.5 cm is allowed to float vertically in water by placing 10.4g of mercury at the bottom of the tube. The tube is depressed by a small amount and then released. Find the period of oscillation.

A uniform solid bar of wood floats vertically in water with 10 cm of its height immersed in the water. When it is slightly depressed and released, it oscillates with a frequency of

A capillary tube of radius 0.20 mm is dipped verticaly in water. Find the height of the water column raised in the tube. Surface tensionn of water =0.075Nm^-1 and density of water =1000 kgm^-3. Take g=10 ms^-2 .

The length of a weigtless spring increaes by 2cm when a weight of 1.0kg in the period of oscillation of the spring and its kinetic energy of oscillation. Take g=10ms^(-2) .

A cubical body (side 0.1m and mass 0.002kg) floats in water. It is pressed and then released so that it executes SHM. Find the time period. (g=10m//s^(2))

A wooden cylinder of mass 20 g and area of cross-section 1 cm^(2) , having a piece of lead of mass 60g attached to its bottom, floats in water. The cylinder is depressed and then released. The frequency of oscillation is ( N )/(pi ) S^(-1) . Find the value of N. [Neglect the volume of water displaced by the lead piece, take g =9.8m//s^(2) ,density of water rho_(w ) = 1 g cm^(-3) ]

The column of mercury in a barometer is 76 cm Hg. Calculate the atmosphere pressure I the density of mercury =13600kgm^(-3) (Take g=10ms^(-2) )
