Question

Question 4-4 points Swimming E. coli travel at a constant speed, but change direction after random time intervals to create a zig-zag path. The figure below shows the path taken by a single E. coli, the positions in space where it changes direction are labeled A, B, C etc. A segment of the E coli's motion can then be identified by two letters i.e. BC for example. During which segments, if any, does the bacterium: (a) Travel the same distance? (b) Travel through the same displacement? (c) Travel with the same speed? (d) Travel with the same velocity?

Explanation / Answer

Ans.

(c) Travel with the same speed

explanation - because the swimming of the E.coli is constant speed. So it travel with the same speed in between two letters
