Answer: density of material pm = 693.2kg/m^3
Explanation:
Using Archimedes principle.
The buoyancy force equals the weight of material submerged which equals the weight liquid displaced.
Fb = Wm = Wl
I.e
Wm = Wl
pm . Vm . g = pl . Vl .g
pm .Vm = pl . Vl
pm/pl = Vl/Vm
Where; pm and pl are the density of material and liquid oil respectively.
Vm and Vl are the volume of material and volume liquid displaced respectively.
g is the acceleration due to gravity
Fb is the buoyancy force
Wm and Wl are the material weight and liquid displaced weight respectively
Given that the material displaced 75.1% of the volume of the liquid oil
VI/Vm = 0.751
pm/pl = 0.751
pm = 0.751pl
density of oil is 923kg/m^3
pm = 0.751× 923
pm = 693.2kg/m^3
The theory for the hydrogen atom based on quantum theory that energy is transferred only in certain well defined quantities. Electrons should move around the nucleus but only in prescribed orbits. When jumping from one orbit to another with lower energy, a light quantum is emitted.
