Also, why is the first ionization energy of aluminum less than the first ionization energy of magnesium?And explain why the electron affinity of Be very small or zero and the electron affinity of F very large? (328 kJ/mole)
aluminum is a metal, therefore it wants to lose elctrons to achieve ideal shells, magnesium on the other hand will want to steal electronsSo in general aluminum will have low ionization energy and low electron affinity while magnesium will have high ionization and high affinity, assuming that affinity refers to ability to steal electrons.
Force weight of ball + weight of cable F(y) 1000 + 10(30 - y) 1300 - 10y, where y is length of cable already lifted upW ∫ F(y) dy ∫??? (1300 - 10y) dy (1300y - 5y?)|??? 39000 - 4500 34500 ft-lb
