A denatured (long, wiggly) protein placed in water folds into one specific conformation so that is can perform some specific function, such as facilitating a chemical reaction (enzyme) or transporting atoms in a cell. Since the wiggly, denatured state has more configurations than the precise folded conformation, the entropy of the protein decreases as it folds in water. Why then is this process spontaneous

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.
