25. The above table shows successive ionization energies for an unknown element from
period 3. What is the unknown element?
a. Na
b. Mg
C. AI
d. si
e. P

increased stability in the completion of fluorine's outer shell.

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.
