A container partially filled with water is moved horizontally with acceleration α=g/3. A small wooden block of mass m is tied to the bottom of the container using a string. The block remains inside. Water with the string inclined at an angle θ to the horizontal. Assuming that the density of wood is half the density of water, fnd the angle θ and the tension inthe string.

A cyclindrical ice block is floating in water 10% of its total volume is outside water. Kerosene oil (relative density=0.8) is poured slowly on top of water in the container. Assume that the oil does not mix with water. Height of the ice cylinder is H. (a) As kerosene is poured, how does the volume of ice block above the water level change? (b) What is the thickness of kerosene layer above the water when 20% of the volume of the ice block is above the water surface? (c) Find the ratio of voume of ice block is kerosene to its volume in water after the kerosene layer rises above the top surface of ice and the block gets completely submerged. Neglect any melting of ice.
