Answer:
The frequency of wing flutters per second is 80.
Explanation:
Frequency is defined as the number of waves that passes a given point per second. It is expressed in Hertz that second inverse.
[tex]1 Hertz = 1 s^{-1}[/tex]
Number of times wings fluttered by hummingbird = [tex]4800 min^{-1}[/tex]
1 minute = 60 seconds
Frequency wing flutters per second = F
[tex]F = 4800 min^{-1}=\frac{4800}{60 s}=80 s^{-1}[/tex]
The frequency of wing flutters per second is 80.
