Question

рыбак, наблюдая за волнами, оценил расстояние между гребнями волн (5 м) и время (48с) прохождения мимо него 10 полных волн. какова скорость распространения волн? (конечный ответ округлите до десятых) ​

Answer 1

Дано:

λ=5 м

t=48 с

N=10

υ-?

Решение:

T=t/N=48/10=4,8 с

λ=υT => υ=λ/T=5/4,8≈1,0 м/с

Ответ:υ≈1,0 м/с.

Answer 2

Calculating Wave Speed

To calculate the speed of the waves, we can use the formula:

Wave speed = Distance / Time

In this scenario, the fisherman observed a distance of 5 meters between wave crests and a time of 48 seconds for 10 complete waves to pass.

Calculation

Using the given values: - Distance = 5 meters - Time for 10 waves = 48 seconds

We can calculate the wave speed as follows:

Wave speed = 5 meters / 48 seconds

Result

Calculating the wave speed: - Wave speed = 5 / 48 = 0.104166... m/s

Rounding to one decimal place, the speed of the waves is approximately 0.1 m/s.
