evablogger [386]

Answer:

3) 0.75m/s

Explanation:

The wavelength of a wave is calculated using the formula;

λ = v/f

Where!

λ = wavelength of wave (m)

v = velocity or speed (m/s)

f = frequency of wave (Hz)

According to this question, one end of a rope is vibrated to produce a wave with a wavelength (λ) of 0.25 m and frequency (f) of 3.0 Hz.

Using λ = v/f

v = λ × f

v = 0.25 × 3

v = 0.75m/s.

2-The existence of oil fields, or oil towers for the manufacture of fuel.

3-Implement electric cars or batteries that do not depend on fuels such as diesel, naphtha.

Explanation:

In this exercise it is good to highlight that during the migration of animals of different species their numbers decreased both to reach the territory to which they migrate and by human intervention in nature in a harmful way.
