Physics: Principles with Applications 7
A pendulum consists of a mass M hanging at the bottom end of a massless rod of length which has a frictionless pivot at its top end. A mass m, moving as shown in Fig. 735 with velocity v, impacts M and becomes embedded. What is the smallest value of v sufficient to cause the pendulum (with embedded m

Epinephrine initiates a signal transduction pathway that involves production of cyclic AMP (cAMP) and leads to the breakdown of glycogen to glucose, a major energy source for cells. But glycogen breakdown is actually only part of the fight-or- flight response that epinephrine brings about; the overal
