Ahummingbird can a flutter its wings 4800 times per minute what is the frequency of wing flutters per second

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.

Number of times wings fluttered by hummingbird =

1 minute = 60 seconds

Frequency wing flutters per second = F

The frequency of wing flutters per second is 80.

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
