20. The fact that two large ships travelling on close parallel courses in the same direction tend to move towards each other can be explained by A.Bernoulli's principle B.Magnetic properties of the ship's material C.Newton's third law of motion D.Earth's gravitational force
Option A Solution: The fact that two large ships travelling on close parallel courses in the same direction tend to move towards each other can be explained by Bernoulli's principle. The rapid flow of air between the two moving ships causes a reducton of pressure (Bernoulli's principle) , so they (the ships) are drawn closer together.
