A cubical block of wood weighing 200 g has a lead piece fastened underneath. Find the mass of the lead pieces which will just allow the block to float in water. Specific gravity of wood is 0.8 and that of lead is 11.3 . (b) Solve the previous problem if the lead piece is fastened on the top surface of the block and the block is to float with its upper surface just dipping into water.

In the previous problem , if the applied force is made 20 N , the acceleration of the upper and the lower blocks will be

Solve the previous problem if the paperweight is inverted at its place so that the spherical surface touches the paper

Solve the previous problem if the paperweight is inverted at its palce so that the spherical surface touches the paper.

In the previous problem , the bullet penetrates the block and emerges with speed v_(0) .If the block travels 2.5 m on the rough surface , the value of v_(0) is

A wooden block of cross sectional area A (in shape of a rectangle) has height h. It is held such that its lower surface touches the water surface in a wide and deep tank. The block is released in this positon. It oscillates for some time and then settles into its equilibrium positon. in equilibrium the block floats with its upper face just on the water surface. Calculate the amount of heat generated in the process assuming that the loss in gravitational potential energy of the system coprising of water and the block gets converted into heat. Density of water is rho .

Why does a block of plastic immersed under water come to the surface of water ?

A block of wood of weight 200 g floats on the surface of water. If the volume of block is 300 cm^(3) calculate the upthrust due to water.

All surfaces are smooth. Find the horizontal displacements of the block and wedge when the block slides down from top to bottom.
