Answer:
The energy absorbed by the atomic electrons in the mercury atom is 
J
Explanation:
Given:
Potential 
V
According to the conservation law,
Loss in kinetic energy = Gain in potential energy
Here, energy absorbed by the atomic electrons is given by,
Where 
( charge of electron )
J
Therefore, the energy absorbed by the atomic electrons in the mercury atom is J
Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. ... Velocity is the rate at which the position changes. The average velocity is the displacement or position change (a vector quantity) per time ratio.
HCl is a strong electrolyte and when it dissolves in water it separates almost completely into positively - charged hydrogen ions and negatively - charged chloride ions. This aqueous solution is usually called hydrochloric acid.
When the velocity of an object changes, it is acted upon by a force
