a) A block of wood (density 600 kg / m3) has a length of 40 cm,
a width of 30 cm and a height of 20 cm
How much percentage of the total volume is submerged in oil of
density 950 kg / m ^ 3?
b) Force required to remove a circular plug of 0.02 meters radius
from a bathtub whose water level is 0.5 m high with respect to the
bottom of it?
Consider the density of water as 1000 kg / m^3
Pressure inside the drain pipe P0 = 1 atm = 101300 Pa.

2. 95% of a wood block is submerged in water (density= 1000 kg/m). A layer of oil with a density of 880 kg/m' is now poured on top, to a depth that more than covers the block, as shown. Find the resulting new volume fraction submerged in water, V(in water) / V(block). Hints: (i) You get two buoyant forces - one for each liquid; Also note that (ii) volume, V(block) = V(in water) + V(in oil). d=880 kg/m² V =...

A U-tube contains liquid of unknown density. An oil of density
770 kg/m³ is poured into one arm of the tube until the oil column
is 13.5 cm high. The oil-air interface is then 4.5 cm above the
liquid level in the other arm of the U-tube. Find the density of
the liquid.

IP A block of wood floats on water. A layer of oil is now poured on top of the water to a depth that more than covers the block, as shown in the figure(Figure 1). If 93 % of the wood is submerged in water before the oil is added, find the fraction submerged when oil with a density of 865 kg/m3 covers the block. Express your answer using two significant figures.
