because it was evident that they did not have enough energy, according to classical physics, to escape the nucleus. Once an approximate size of the nucleus was obtaine by Rutherford scattering, one could calculate the height of the Coulomb barrier at the radius of the nucleus. It was evident that this energy was several times higher than the observed

alpha particle energies. There was also an incredibl How long does it take for the ball to hit the ground? (5 marks) 3. a. i. Solve for x : 25????+3 = 125???? (1 mark) ii.
