Question

Частота колебаний крыльев вороны в полёте равна в среднем 3 гц.сколько взмахов крыльями сделает ворона ,пролетев путь 650 м со скоростью 13м/с

Answer 1

Дано:
γ=3Гц
L=650м
V=13м/с
N-?
γ=N/t, выразим число колебаний
N=γ*t
Пройденный путь = произведению скорости на время L=V*t
выразим время t=L/V
найдем время полета птицы  t=650м/13м/с=50с
найдем число взмахов крыльями N=3Гц*50с=150
150 взмахов крыльями сделает ворона

Answer 2

Calculation of Wing Flaps by a Crow

To calculate the number of wing flaps made by a crow while flying a distance of 650 meters at a speed of 13 m/s, we need to use the given information about the frequency of wing oscillations.

The frequency of wing oscillations of a crow in flight is stated to be an average of 3 Hz.

We can use the formula:

Frequency (f) = Number of oscillations (n) / Time (t)

Rearranging the formula, we get:

Number of oscillations (n) = Frequency (f) * Time (t)

To find the time taken to cover a distance of 650 meters at a speed of 13 m/s, we can use the formula:

Time (t) = Distance (d) / Speed (v)

Substituting the given values:

Time (t) = 650 m / 13 m/s = 50 seconds

Now, we can calculate the number of wing flaps made by the crow:

Number of oscillations (n) = 3 Hz * 50 seconds = 150 wing flaps

Therefore, the crow will make approximately 150 wing flaps while flying a distance of 650 meters at a speed of 13 m/s.

Please note that this calculation assumes a constant frequency of wing oscillations throughout the flight and does not account for any variations or adjustments made by the crow during the flight.
