Which of the following statements concerning molecular orbital (MO) theory are correct? I. The Pauli Exclusion Principle is obeyed. II. Hund's rule is obeyed. III. a bonding molecular orbital is lower in energy than its parent atomic orbitals IV. the combination of two atomic orbitals creates one molecular orbital V. an antibonding molecular orbital is lower in energy than its parent atomic orbitals

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
