6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>2.16 moles</h3>
Hope this helps you
Answer:
By minimizing the height of the body's center of gravity relative to its center of buoyancy
Explanation:
In hydrostatics, the equilibrium state of a floating body relates to either a maximum or minimum of the potential energy.An equilibrium is stable when the potential energy is minimum.Minimizing the height of the floating body's center of gravity relative to its center of buoyancy attains a stable equilibrium configuration.
the answer is d. this is due to the fact a proton weighs 2000 times more then a electron
