Answer 2

Based on the search results, it seems that you are asking about a scenario involving a turntable with a small object on its edge and a stopwatch. The turntable is set in motion, causing the object to move in a circular path. You want to determine the time it takes for the object to complete 30 revolutions.

To calculate the time taken for the object to complete 30 revolutions, we need to know the rotational speed of the turntable. Unfortunately, the information provided does not include the rotational speed. Without this information, it is not possible to determine the time taken accurately.

If you have any additional information or if there is something specific you would like to know, please provide more details, and I'll be happy to assist you further.
