5.7 kilometers is equal to 3.5418157957528034 miles
Gravitational force decreases with increasing distance. So it decreases!
Answer:
3.53*10^{-7} m
Explanation:
Photon that can rupture the bonds are those with the energy of the bond dissociation energy. If we want to know the energy for each molecule we have to take into account that:

Hence, we have

but the energy is also:

where h is the Planck's constant and c is the speed of ligth. By replacing we obtain:

hope this helps!
