Problem 70CP

FIGURE shows a particle of mass m at distance x along the axis of a very thin ring of mass Mand radius R.

a. Calculate the gravitational potential energy of these two masses.

b. Use what you know about the relationship between force and potential energy to find the magnitude of the gravitational force on m when it is at position x.

Metabolism ***FOR EXAM it is most important to know basic concepts along w/ reactants, products & enzymes/cofactors and where things happen – specific intermediate steps are not as important. Make sure to know how much of each product is produced from each step (glycolysis, Krebs/Citric Acid cycle, etc. for a given amount of a certain reactant!*** ATP (Adenosine Triphosphate) – cellular energy currency Made from adenine, ribose & 3 phosphate groups ATP Hydrolysis fun fact: every day you turn over (breakdown & resynthesize) an amount of ATP roughly equivalent to your body weight! Cellular movement, molecular synthesis, & transport across membranes all require ATP Phosphocreatine (PCr) Creatine phosphate + ADP -> creatine k
