No force is necessary to keep a moving object moving (in a straight line at a constant speed).
Wavelength of the water wave is 8 m
Explanation:
- Wavelength measures the distance between two successive crests or troughs of the wave. It is given by the following equation
λ = v/f, where f is the frequency, v is the velocity of the wave
Here, v = 20 m/s and f = 2.5 Hz
⇒ λ = 20/2.5
= 8 m
The answer is X. I hope this helped
Answer:
c it is not accelerating on it's on but gravity pulls it there for velocity increases.
