Determine the magnitudes and directions of the currents in each resistor shown in the figure. The batteries have emfs of $\mathcal{E}_1 = 7.4$ V and $\mathcal{E}_2 = 12.0$ V and the resistors have values of $R_1 = 26 \Omega$, $R_2 =$ $38 \Omega$, and $R_3 = 39 \Omega$ (Figure 1) Ignore internal resistance of the batteries. Express your answers using two significant figures. Enter your answers numerically separated by commas. $I_1, I_2, I_3 =$ $I_1$ is directed to the left. $I_1$ is directed to the right. $I_2$ is directed to the left. $I_2$ is directed to the right.

(b) A flavoured syrup is mixed with water in a mixing unit. Water and syrup are flowing with speed 2 m/s into the mixing unit through circular pipes of cross-section area 9 cm² and 2 cm² respectively. The homogeneous mixture of water and syrup has density 1200 kg/m³. It exits the mixing unit with a speed of 1.25 m/s through a circular pipe of 16 cm² and is poured into a tank of base area 6 m², as shown on Figure 3. (i) Assuming that the mass of fluids inside the mixing unit remains constant, determine the density of the syrup. (4 marks) (ii) If the tank is initially empty, determine the depth h of water-syrup mixture in the tank after 5 hours. (6 marks) (Total for question: 20 marks)
