A solid insulating sphere has radius a = 3.2 meters and total charge Q = 3.6 Coulomb's. Calculate the potential difference between the center of the sphere and a point r = 0.64 meters from the center of the sphere. (A positive answer represents the center is at a lower potential, a negative answer corresponds to the center being at a higher potential.) ...

An electron accelerated through a potential will gain a kinetic energy of 110eV (electron volts). KE = 0.5mv^2 p = mv therefore your momentum, p = sqrt(KE * m *2). To convert electron volts to Joules (SI unit of energy) multiply by 1.6x10^-19. So you have 1.76x10^-17 Joules of energy. The mass of an electron is 9.11x10^-31 kg so; p = 5.66x10^-24 kg m/s the de Broglie ...

So? It still does not negate the statement that “Whether or not childhood trauma can be overcome is strictly up to the individual”. Nope it doesn't. It does minimize it however. Individuals can overcome circumstances or learned behavior. Most don't.
