Question

to compare the velocities of different parts of a stream, five similar floating objects are placed in the stream at points a through e at station 1. if the five objects are released at the same time, what is the most probable arrangement of the objects as they approach station 2?

Explanation:

Step1: Recall fluid - flow principle

In a stream, the velocity is higher in the middle and lower near the banks due to friction.

Step2: Analyze object positions

Objects in the middle of the stream will move faster than those near the banks. So, the objects in the middle - most positions at the start will reach Station 2 first.

Answer:

The objects in the middle - most positions at Station 1 will be ahead of those near the banks as they approach Station 2. (Since no specific options for arrangements are given in the text, this is a general description of the expected arrangement. If there were visual options, we would choose the one that shows the middle - starting objects in the lead).
