Question

Определить число колебаний груза на пружине за время,равное 20с, если частота его колебаний равна 4Гц. Чему равен период колебания?

Answer 1

Т=t/N; ню=N/t; N= ню*t
N=20*4=80
T=20/80=1/4

Answer 2

Calculating the Number of Oscillations and Period of Oscillation

To determine the number of oscillations of a mass on a spring in a given time and the period of oscillation, we can use the formula:

Number of oscillations (N) = Frequency (f) × Time (t)

Given that the frequency of oscillation is 4 Hz and the time is 20 s, we can calculate the number of oscillations using the formula:

Number of oscillations (N) = 4 Hz × 20 s

Using this formula, we find that the number of oscillations is 80.

Next, to find the period of oscillation, we can use the formula:

Period (T) = 1 / Frequency (f)

Given that the frequency is 4 Hz, we can calculate the period of oscillation using the formula:

Period (T) = 1 / 4 Hz

Using this formula, we find that the period of oscillation is 0.25 seconds.

Therefore, the number of oscillations of the mass on the spring in 20 seconds is 80 oscillations, and the period of oscillation is 0.25 seconds.
