Question 1 The femoral artery carries blood to the leg and has a diameter of 10.2 mm. What is the resistance in a column of blood that is 2.00 cm long if the conductivity of blood is 0.630 0 m-1? O 1540 0 97.10 O 1.22x103 0 O 389 0 Question 2 WW R V1 V 2 + The figure shows two batteries and a resistor all connected in series. The first battery has a voltage if 4.90 V, the second battery has a voltage of 8.70 V and the resistor has a resistance of 17.0 0. What is the current through the resistor and in what direction does it flow? O 0.224 A, counterclockwise O 0.800 A, clockwise 0.800 A, counterclockwise O 0.224 A, clockwiseQuestion 3 A 10.1 V battery has some internal resistance. When a 26.0 0 resistor is connected the voltage across the terminals drops to 6.60 V. What is the battery's internal resistance? 43.0 0 O 263 0 O 13.8 0 O 172 0
