Question

Длина морской волны равна 2 м. Какое количество колебаний за 10 с совершит поплавок, если скорость распространения волны равна 6 м/с.

Answer 1

Calculation of the Number of Oscillations

To calculate the number of oscillations a float will complete in 10 seconds, we need to determine the time period of one oscillation. The time period is the time it takes for one complete cycle of oscillation.

The formula to calculate the time period is:

Time Period (T) = Distance / Velocity

Given: - Length of the wave (Distance) = 2 meters - Velocity of wave propagation = 6 m/s

Substituting the values into the formula, we get:

T = 2 meters / 6 m/s

Simplifying the equation, we find:

T = 1/3 seconds

Now, we can calculate the number of oscillations in 10 seconds by dividing the total time (10 seconds) by the time period of one oscillation (1/3 seconds):

Number of Oscillations = Total Time / Time Period

Substituting the values, we get:

Number of Oscillations = 10 seconds / (1/3 seconds)

Simplifying the equation, we find:

Number of Oscillations = 30 oscillations

Therefore, the float will complete 30 oscillations in 10 seconds.
