An ice floe is floating in the sea. The part which is above the water is a prism of height `0.5 m`. A `200 kg` seal climbs onto the floe, which sinks `5cm` deeper into the water. How many seals, which have the same mass, can the floe hold without sinking totally into the water ?

A piece of ice floats in a vessel with water above which a layer of a lighter oil is poured. How will the level of the interface change after the whole of ice melts? What will be the change in the total level of liquid in the vessel?

There are two cylinder shaped wooden billets, each having a mass of mass 45kg , in a vertical wall sewage, which contains water in it. the two billets have the same size and the same material, they touch each other and the walls of the sewage. One of them is totally under the water, whilst only half of the other one is immersed into the water. Friction is negligible everywhere. (density of water is 1000kg//m^(3) and g=10m//s^(2) ). Choose the correct option(s)
