A cubical block of wood of edge $10 \mathrm{cm}$ and mass $0.92 \mathrm{kg}$ floats on a tank of water with oil of relative density$0.6.$ Thickness of oil is $4 \mathrm{cm}$ above water. When the block attains equilibrium with four of its sides edges vertical:

A wooden block with a coin placed on its top, floats in water as shown in figure. The distance $l$ and $\mathrm{h}$ are shown here. After some time the coin falls into the water. Then :

A cylindrical vessel of$90 \mathrm{cm}$height is kept filled up to the brim as shown in the figure. It has four holes $1, 2, 3, 4$which are respectively at heights of $20 \mathrm{cm}, 30 \mathrm{cm}, 40 \mathrm{cm}$ and $50 \mathrm{cm}$ from the horizontal floor $PQ.$ The water falling at the maximum horizontal distance from the vessel comes from

Statement-$1$: The stream of water flowing at high speed from a garden hose pipe tends to spread like a fountain when held vertically up, but tends to narrow down when held vertically down.

Statement-$2$: In any steady flow of an incompressible fluid, the volume flow rate of the fluid remains constant.

Two solid spheres $A$ and $B$ of equal volumes but of different densities $d_A$ and $d_B$  are connected by a string. They are fully immersed in a fluid of density $d_F.$ They get arranged into an equilibrium state as shown in the figure with a tension in the string. The arrangement is possible only if

A person in a lift is holding a water jar, which has a small hole at the lower end of its side. When the lift is at rest, the water jet coming out of the hole hits the floor of the lift at a distance $d=1.2 \mathrm{m}$ from the person. In the following, the state of the lift's motion is given in $\mathrm{List}-\mathrm{I}$ and the distance where the water jet hits the floor of the lift is given in $\mathrm{List}-\mathrm{II}.$ Match the statements from $\mathrm{List}-\mathrm{I}$with those in $\mathrm{List}-\mathrm{II}$ and select the correct answer using the code given below lists.
