Answer 1

flutters per second is 80 and the period is 0.013.

Step-by-step explanation:

i just took the test.

Answer 2

f = 80 flutter/ second

T= 0.0125 sec

Step-by-step explanation:

Given data:

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
