Analyze given skill in the chart, and list the movements of the right and left knee joints in each phase of the skill. You may prefer to list the initial position the knee joint is in for the stance phase. After each movement, list the knee joint muscle(s) primarily responsible for causing/controlling the movement. Beside each muscle in each movement, indicate the type of contraction as follows: I-isometric; C-concentric; E-eccentric.
Calculate the standard emf of a cell that uses the Mg/Mg2+\mathrm{Mg}/\mathrm{Mg}^{2+}Mg/Mg2+ and Cu/Cu2+\mathrm{Cu} / \mathrm{Cu}^{2+}Cu/Cu2+ half-cell reactions at 25∘C25^{\circ} \mathrm{C}25∘C. Write the equation for the cell reaction that occurs under standard-state conditions.
