Dear public, our ecosystem is being ruined and we need to stop it, i think you should do something about the littering and loitering in our community and in the U.S. it would help a lot of people if you made a law against it or if we went out and all did community service and helped pick up. if you don't like these ideas we could protest, but all me and my fellow people ask is that you help our <span><span>ecosystem for better lives for everyone! yours truly, citizen</span></span>
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.
