Answer:
28.295244 MeV
Explanation:
= Mass of proton = 1.007276 u
= Mass of neutron = 1.008665 u
= Mass of electron = 0.000549 u
Mass of reactant is 4.002604 u
Mass of the products is

(2 because there are 2 of each)
The difference in mass is

So, the work done in MeV would be

The work done required to completely disassemble all the helium is 28.295244 MeV
Work = (force) x (distance)
If the distance is zero (the object doesn't move), then it
doesn't matter how great the force is. The work is still zero.
The are elements on the periodic table
Newton's Third Law states that for every action there is an opposite and equal reaction:
If the gravitational force of the Earth on the Moon is F then the gravitational force of the Moon on the Earth is also F
