Final answer:
To determine the minimum duration for a fixed wind speed in an experiment, use a consistent wind source, an anemometer, and a stopwatch to measure how long it takes for objects to travel a set distance in the wind stream, and record the data in a table.
Step-by-step explanation:
To set up an experiment to determine the minimum duration for a fixed wind speed, you will need a wind source like a fan, an anemometer to measure wind speed, and a stopwatch to measure duration. First, set the fan at a specific distance from the testing area to ensure a consistent wind speed. Use the anemometer to verify this speed. Then, use objects of different weights and shapes as test subjects, and release them from a fixed height specifically affected by the wind stream. Utilize the stopwatch to measure how long each object takes to move a set distance within the wind stream. Repeat the test multiple times for accuracy and consistency.
Collect your data in a table, noting the duration each test subject takes to travel the set distance under the constant wind speed. By analyzing the data, you will identify the minimum time duration at which the wind is capable of conveying the different objects across the fixed distance, thus achieving your experimental objective.
