Light no. 10 oil is heated from 95°f to 105°f in a 0.6 in inside diameter tube. the average velocity of the oil is 2.0 ft/sec. the viscosity of the oil at 100°f is 45 centistokes (cs). what is the reynolds number inside the tube?

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
