According to archimedes’ principle, the mass of a floating object equals the mass of the fluid displaced by the object. use this principle to solve the following problems. (a) a wooden cylinder 30.0 cm high floats vertically in a tub of water (density 1: 00 g/cm3 ). the top of the cylinder is 13.5 cm above the surface of the liquid. what is the density of the wood? (b) the same cylinder floats vertically in a liquid of unknown density. the top of the cylinder is 18.9 cm above the surface of the liquid. what is the liquid density? (c) explain why knowing the length and width of the wooden objects is unnecessary in solving parts (a) and (b).

Part a)
Part b)
Part c)
Since we know that the base area will remain same always
so here the length and width of the object is not necessary to obtain the above data in such type of questions
Explanation:
Part a)
As we know that when cylinder float in the water then weight of the cylinder is counter balanced by the buoyancy force
So here we know
buoyancy force is given as
Now we know that the weight of the cylinder is given as
now we have
Part b)
When the same cylinder is floating in other liquid then we will have
so we have
Part c)
Since we know that the base area will remain same always
so here the length and width of the object is not necessary to obtain the above data in such type of questions
