If an ice cube a with impurities is floating in the water container and after few minutes ice melts and impurities are sink down then find the level of water in that container :
A beaker containing water weighs $100$ g. It is placed on the pan of a balance and a piece of metal weighing 70 g and having a volume of $10c{m^3}$ is placed inside the water in beaker. The weight of the beaker and the metal would be:
equal to the weight of the immersed part of the body 2 . A raft of wood of mass 120 kg floats in water . The weight C that can be on the raft on make it just sink , should be $(d _{raft} = 600 kg/m _{3} )$
A wooden cube floating in water supports a mass $0.2 kg$ When the mass is removed the cube rises by $2 cm.$ The side of the cube is (density of water=${10^3}kg/{m^3}$)
The material of wire has specific gravity 8. It is not wetted by water, what is the diameter of the wire that will float on the surface of water?(T =70 dy /cm)
A ball rise with constant velocity, to the surface of a liquid whose density is four times that of the ball. The ratio of the v force to weight of the ball is
A balloon has volume of 1000 $m^{3}$ . It is filled with hydrogen ($ \rho $ = 0.09 g/L ) . If the density of air is 1.29 g/L , it can lift a total weight of
An ice cube is floating on the surface of water. How will the water level be affected by melting of this ice cube?
A body is float inside liquid. If we increase temperature then what charges occur in buoyancy force?(Assume body is always in floating condition )
A wooden cube floats just inside the water, when a mass of $x$ (in grams) is placed on it. If the mass is removed, the cube floats with a height $\dfrac{x}{100}\ cm$ above the water surface. The length of the side of cube is (density of water is $1000\ kg/m^{3}$)
