The formation of an action potential can be divided into five steps. (1) A stimulus from a sensory cell or another neuron causes the target cell to depolarize toward the threshold potential. (2) If the threshold of excitation is reached‚ all Na+ channels open and the membrane depolarizes. (3) At the peak action potential‚ K+ channels open and K+ begins to leave the cell. At the same time‚ Na+ channels close. (4) The membrane becomes hyperpolarized as K+ ions continue to leave the cell. The

Salem Witch Trials. He describes several of the deadly conflicts that occur between the townspeople‚ but not all the conflicts were external ones. One such conflict occurred within the expert in all things supernatural‚ Reverend Hale. Hale’s internal conflict happened because he realized fear causes people to make rash decisions‚ so he began to doubt all the work he had been doing in Salem and the Witch Trials as a whole. Hale’s inner conflict begins when John Proctor‚ a town leader‚ brings one the

Discussion and Conclusions Many obstacles to my potential strategy are worth overcoming. Since the brand new policy is to add extra taxes on smoking and fining the smoking companies for their actions‚ then one is able to make sure that people comply or go out of business. A way to overcome the challenges is to have someone from each company represented in Congress (Kottke‚ RN‚ GH‚ & ML.‚ 1988).

examples of work done=force x distance What is work? Work in physics is the transfer of energy; work is done on an object when an applied force moves it through a distance. The link between work and energy is work done equals energy transferred. The units for the two are also the same (joules). E.g. 500J of work = 500J of kinetic energy. Work is calculated with the formula: work done=force x distance moved For example‚ if a force of 10 newton (F = 10 N) acts along point that travels 2 meters

Potential Energy Potential Energy is a type of energy that does not involve motion. It is the energy that is stored up. The more work done to change an object’s position or shape‚ the more potential energy it has. For example‚ a person on a ladder has more potential energy than a person on the ground because they have done more work to get up there. Kinetic Energy Kinetic Energy is the energy of motion. The more work an object has done‚ the more kinetic energy it has. the amount of kinetic

Undoubtedly‚ The Odyssey by Homer uses internal conflicts to reveal Odysseus as a determined character in order to get back to his homeland Ithaca. “He will be the only survivor of their long journey” (italics 780) shows only the strong survive.

But Odysseus is only doing what he thinks was right he knew that telling his men would only entail them in something not meant for them. Telling
