Answer :
After solving, 41.67 Hz wing beats the dragonfly performs per second.
In the given question, if the video is shot at 190 frames per second, then we have to find how many wing beats the dragonfly performs per second.
From the given question,
Frames per one wing beat = 6 frames
Video shot at = 250 frames per second
We firstly find the time period
So, Time period (T) = 6/250
T= 0.024 s
Snce we have to find how many wing beats the dragonfly performs per second.
Per second number of wing beats = 1/T
Per second number of wing beats = 1/0.024
Per second number of wing beats = 41.67 Hz
Hence, 41.67 Hz wing beats the dragonfly performs per second.

The right question is;
A frame by frame analysis of a slowmotion video shows that a hovering dragonfly takes 6 frames to complete one wing beat.
If the video is shot at 190 frames per second, how many wing beats does the dragonfly perform per second?
