Taking into account the definition of density and Archimedes' principle, the beginner bowling ball will float on the water.
But first it is neccesary to know that density is a quantity referred to the amount of mass in a certain volume of a substance or a solid object.
In other words, the density is the relationship between the weight (mass) of a substance and the volume that the same substance occupies.
The expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:
In this case, a beginner's bowling ball has a mass of 4.9 kg and a volume of 5.4 liters. This is:
- mass= 4.9 kg= 4900 g (being 1 kg= 1000 kg)
- volume= 5.4 L= 5400 mL (being 1L=1000 mL)
Replacing in the definition of density:
Solving:
<u><em>density=0.907 </em></u><u><em /></u>
On the other hand, Archimedes' principle says that an object immersed in a liquid experiences an upward vertical force equal to the weight of the volume of the dislodged liquid.
The sinking or floating of an object is determined by its density with respect to that of the liquid in which it is submerged.
Considering water as the liquid where the object is submerged in this case, an object with a higher density than water will sink. In contrast, an object with a lower density than water will float.
In this case, considering that water has a density of 1 , the bowling ball for beginners has a lower density. This indicates that, having a lower density than water, the object will float.
In summary, the beginner bowling ball will float on the water.

Answer:
the amounts and compositions of the overflow V1 and underflow L1 leaving the stage are 75kg and 125kg respectively.
Explanation:
Let state the given parameters;
Let A= solvent (hexane)
B= solid(inert soiid)
C= solvent(oil)
= mass of solvent + mass of oil (i.e A+C)
<u>Feed Phase:</u>
Total feed (i.e slurry of flakes soybeans)= 100kg
B= mass of solid =75 kg
F= mass of solvent + mass of oil (i.e A+C)
= 25kg
Mass ratio of oil to solution =
mass of oil (C) =25 × 0.1 wt = 2.5kg
mass of hexane in feed = 25 × 0.9 =22.5kg + 2.5 =25kg
therefore =
= 0.1
mass ratio of solid to solution =
=3
<u>Solvent Phase:</u>
C= Mass of oil= 0(kg)
A= Mass of hexane = 100kg
mass of solutions = A+C = 0+100kg
solvent= 100kg
<u>Underflow:</u>
underflow = L₁ = (unknown) ???
L₁ = E₁ + B
the value of N for the outlet and underflow is 1.5 kg
i.e N₁ =
solution in underflow E₁ = Mass (A+C)
<u>Overflow:</u>
Overflow = V₁ = (unknown) ???
solution in overflow V₁ = Mass (A+C)
This is because, B = 0 in overflow
Solid Balance: (since the solid is inert, then is said to be same in feed & underflow).
solid in feed = solid in underflow = 75
75= E₁ × N₁
75 = E₁ × 1.5
E₁ = 50kg
Underflow L₁ = E₁ × B
= 50 + 75
=125kg
The Overall Balance: Feed + Solvent = underflow + overflow
100 + 100 = 125 + V₁
V₁ = 75kg
