The heart pumps oxygenated blood into arteries, and the blood is then circulated around the body. a) Consider a ventricular contraction that accelerates a mass m of blood from rest into an artery oriented in a horizontal direction. To simplify the problem, assume the blood slides along the walls of the artery without friction, like a block of ice on a frozen pond. Also, assume there are no other forces pushing the blood in the horizontal direction. Draw a free body diagram for the blood. Label each force with "by" and "on" subscripts (e.g. F_(by A on B)

QUESTION 4 4.1 Calculate the pH for the following: 4.1.1 A solution made by dissolving 455 mg of sodium acetate ($NaC_2H_3O_2$) in enough water to make a 200 cm$^3$ of solution. [$K_a$ (Acetic acid, $CH_3COOH$) = $1.80 \times 10^{-5}$] 4.1.2 A mixture of 120.0 cm$^3$ of 0.300 M $CH_3COOH$ and 65.0 cm$^3$ of 0.300 M $NaOH$. 4.2 Suppose you wish to recover silver from aqueous solution that contains a soluble silver compound such as $AgNO_3$ by precipitating insoluble silver chloride, $AgCl$. A soluble ionic compound such as $NaCl$ can be used as a source of $Cl^-$. What is the minimum concentration of chloride ion needed to reduce the dissolved silver ion, $Ag^+$ concentration to a maximum of $1.0 \times 10^{-9}$? $K_{sp}$ for $AgCl$ is $1.8 \times 10^{-10}$ (10) (10) (5) [25]
Suppose that the plane tangent to the surface $z = f(x, y)$ at $(7, 12, 13)$ has equation $z + 13x - 7y = 20$. Estimate $f(7.1, 12.1)$. (Use decimal notation. Give your answer to three decimal places.) f(7.1, 12.1) \approx
2. XYZ Company sells cell phone screen protector for $25 each after purchasing from the wholesaler. The markup is 24% of regular selling price, and the owners require a profit that is 10% of regular selling price. (a) For how much does XYZ Company pay to buy a cell phone screen protector from the wholesaler? (b) What is the price needed to cover all of the costs and expenses? (Hint: consider finding the expense (E) first based on the markup amount (M).)
Question 14 (5 marks) The dynamic behavior of a physical system is represented by the transfer function: $\frac{Y(s)}{X(s)} = \frac{18}{s^2 + 3s + 9}$ For a step change of magnitude 3, what will be the maximum deviation from the final steady state?
