Quick

Check

A hummingbird can flutter its wings 4,800 times per minute.

What is the frequency of wing flutters per second?

flutters/second

What is the period for one wing flutter in seconds?

flutters per second is 80 and the period is 0.013.

Explanation:

i just took the test.

f = 80 flutter / second

T = 0.0125 sec

Explanation:

Given dа ta:

Fluttering of wings = 4800 time per minute

Frequency of wings = ?

Period for one wing in sec = ?

Solution:

There are 60 seconds in one minute, thus frequency of wings

4800/60 = 80 flutter per second

Period:

T = 1/f

T = 1/80

T = 0.0125 sec
